Due Kernel I/O error, system refuses to boot randomly

[gary4gar]

My system refuses to boot randomly .
here is the error

[ 52.308000] ata2.00: exeception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
[ 52.308000] ata2.00: cmd c8/00:08:d6:4a:89/00:00:00:00/e2 tag 0 cdb 0x0 data 4096 in
[ 92.568000] ata2.00: revalidation failed (errno=-5)
[ 137.832000] ata2.00: revalidation failed (errno=-5)

now after this, all process started by init are reporting I/O errors
eg.

* Running local boot scripts (/etc/rc.local) [ OK ]
etc/init.rc/: 2:/etc/rc2.d/S99stop=readhead: Input/output error

and lastly i get this message,after this there are no further messages and i am forced to reboot it via REISUB

Buffer I/O error on device sda2, logical block 0

Here is Bit of information about my system

Amd Athlon 64 3000+
MSI-k8mm-v
1 GB drr 400 RAM
Nvidia 6200 128MB Graphics
Seagate ST380815AS(just 2 months old)
Ubuntu 7.10 x86
Kernel 2.6.22-14-generic

I am dual booting it with Windows xp Sp2.

I suspect this error is related to SATA driver,HDD, SATA II backwards compatibility & sata port on my system.

Here is some more information.

Yes this is due to SATA HDD
By any chance u hav enabled AHCI mode ?

even sometime my system refuses to boot and shows similar error, i press restart button and it boots up fine

[praka123]

@gary:seems to me,earlier symptoms of a hdd failure,esp that "frozen" err mesg.I may be wrong,but I got the same error message last time.
I think you should try seatools windows(installer) or livecd to verify that ur hdd is OK.

I have tested it with seatools.
they report it to be working nicely.
and my drive is just 2 months old, replaced it when the old one died
Its brand new 7200.10 series

How to check for AHCI mode?

[praka123]

@gary:then OK .now as per google,it has to do with the newer libata driver and/or the sata connector which tends to be loose.try removing the connector and plugging it again or make sure plugged OK.

and in BIOS,make sure u have enabled all PATA and SATA ports!

[gary4gar]

I am facing this problem at random, which hinders in further debugging.
As, error soon disappears.

it occurs mostly at Worst possible times, like just before i need to take a copy of presentation

Noticed all this errors, over period of 15 days & now posted all information here.


I have tried removing SATA cables, but it does work sometimes & sometimes does not

@prakash
can you point out where you say problems with newer libata driver?

[edit]
seems the problem is widespread, with no workaround available.
more 10,000 results in Google.
http://www.google.co.in/search?q=exc...ion+0x2+frozen

[praka123]

@gary:
its all with the new libata(if u try compiling a kernel,u understand) and ur gr8 mobo(MSI).there was an old sata driver set,but from 2.6.19 onwards libata is the standard.
try booting with "pci=nomsi" in kernel line in grub.also remove quiet splash lines.
https://bugs.launchpad.net/ubuntu/+s...ux/+bug/206635

If all fails,and if ur on x86 architecture,install 2.6.22-386 kernel from apt.

[gary4gar]

One more thing i would like to point out the sata_via driver which i am using is in very bad shape.

even NCQ is disabled, as it does not support.

ata2.00: 156301488 sectors, multi 16: LBA48 NCQ (depth 0/32)

This indicated NCQ is present but disabled, ideally it should be depth 32/32

what is this nomsi thing?

also, i am thinking of upgrading to Hardy x64.

cmd c8/00:08:d6:4a:89/00:00:00:00/e2 tag 0 cdb 0x0 data 4096 in

from this line, i see this driver is at fault

here a resource for all of you
Understanding libata error messages

[gary4gar]

*BUMP*

So Gurus, any solutions to this?

[praka123]

did u tried booting with pci=nomsi option?it seems some specific option for msi mobo.

when grub shows off,press "e" and select "kernel /boot/vmlinuz..." and again press "e" go to the end and append "pci=nomsi" without quotes,press ENTER,then press "b" to boot.

[shady_inc]

Even I face this issue of Kubuntu gutsy refusing to boot randomly.It happens quite frequently now, which is really getting on my nerves now.! KDM starts fine when I boot into recovery mode and start kdm.Tell me the info you guys will need since I don't really know what else should I post to help in identifying the cause.

even many non msi users face this problem, so i do not think nomsi should help.

Still i would try it out & report back

Press ALT+F1 & then ALT+F8.
and see where the system is hanged.

Please post the exact error message

[praka123]

kubuntu is buggy(no,offense).better install ubuntu,then install kde from repo. ,remove gnome.

[gary4gar]

No resolution Yet

Thinking of posting it to KML

[praka123]

I think you may like to try Hardy. ,if hardy too got the same bug,it may be better to complaint on Ubuntu Bug Tracking System(launchpad?).

also try libata mailing list?

[shady_inc]

The problem seems to have gone now that I am using Xfce again.Anyway, I will getting 8.04 and hopefully, the issue won't appear there.

[gary4gar]

heh...i also upgraded to 8.04 x64 in this Hope

My problem occurs random, so can't say if its fixed on hardy.
previous on gutsy it bugged me for 4 days, and didn't occur for next 25 days.

This part is which makes troubleshooting difficult.

[JGuru]

@Gary, Did you send a bug report to the Ubuntu Team about the problems you are
facing? If not, do it immediately. You can also send a report using the "Ubuntu Device Database".

$ hwdb-gui

Nice to see my friends Gary, Mehul, Prakash, Kalpik, Satish, Vishal Gupta, Nitish &
and all others.

Will File a Bug report, if i get the Error again


[offtopic]
@Jguru
Same Here!

[gary4gar]

*BUMP*
Faced this error again. this time things were little different
* Error comes after 2-3 minutes when the machine is fully booted, previously it came during boot-up
* Error Message has been changed a bit but the same message comes again & again.
* This has to do with libata as after Rebooting. i can run windows Xp SP3.
no error messages there

Here is the exact error message(typed the whole thing manually, as system froze)

ata2.00: status: {DRDY ERR}
ata2.00: error: {UNC}
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata2.00: DMDMA stat 0x5
ata2.00: cmd c8/00:08:06:fd:6e/00:00:00:00:/e2 tag 0 dma 4096 in

here is the bug report:https://bugs.launchpad.net/ubuntu/+bug/223014
Hard Luck, Sheer Hard Luck for me

Ps: posting from windows xp, as Ubuntu install is giving me hell lot of problems. so if you ask me to try some command, you have to wait longer.

[praka123]

hmm...bug?for the time being,@gary,you should try a custom compiled kernel which uses old "sata/pata" drivers rather than libata?

one thing is,you can try some old distros with kernel 2.6.15 etc to make sure this is a libata problem.

if that too fails,I am afraid,it will be a hdd problem?

Yeah,will try older kernel. Please guide

@praka123
if it was HDD problem how come windows xp sp3 works fine?

[praka123]

well,I said I am not sure

[gary4gar]

Great, now the problem which was random is permanent, i can't work in 8.04 at all, hangs after boot up

damn, stuck with windows sp

[Faun]

did u try ahci mode ?
