RAID/IDE driver kernel panic (as usual ICH4 problems)

RAID/IDE driver kernel panic (as usual ICH4 problems)

Post by Arne Brutsch » Sat, 28 Jun 2003 00:20:17



Hello,

I'm still having problems with the ICH4 and my PDC20276.

I'm trying to find a stable setup fro the ICH4 since 2.4.18, but
nothing worked till 2.4.21. I always had the resource collisions
and lost interrupts all the others users reported. With this
kernel release (and the ide driver backport), the lost interrupts
vanished. So I recreated my Raid5 and put hapily all data on it.
Now, the lost interrupts are back again. :(

I had serveral lost interrups on some of the ICH4 disks, and this
evening the PDC crashed completely (for the first time). Before that,
the PDC was pretty stable.

More about my hardware setup:

PCI SCSI Controller
   System on /dev/md0-4
onboard ICH4
   2x Maxtor 96147H6, ATA DISK drive, 60GB, /dev/md6
   2x SAMSUNG SV1204H, ATA DISK drive, 120GB
onboard PDC 20276
   4x Maxtor 4G120J6, ATA DISK drive, 120GB

The 120GB drives are /dev/md5, raid level 5. All other raid devices
are raid level 1.

See the thread "[PATCH] ide driver 2.4.21-rc6" starting at 2nd june
about my problems with the PDC20276 and bootorder.

I will include two logs here, sorry for the long mail.

After the crash, I cannot mount the raid 5 disks anymore, it complains
about different superblocks on /dev/hdf5 and /dev/hde5:

Jun 27 00:08:09 gonzo kernel: md5: removing former faulty hdf5!

I hope somebody can help me, and I hope I can get the data back.

My questions are:

1) how can I get the IDE drives stable?
2) how can I get the array (and my data) back?

Regards,
Arne

1. PROBLEM: 2.4.20 on ICH4 : ide-cdrom/ide-scsi problems reading cds

Please cc me directly as I am not subscribed to the list.

I am getting problems (intermittent) trying to play audio CDs using
2.4.20 with an ICH4 controller (although I don't know if the ICH4 is
relevant) - the problem is intermittent and I can eventually play the CD
by ejecting and loading the CD a couple of times. The problem below is
with the ide-cdrom module but it is exacerbated when I use ide-scsi instead.

I have tried this with 2 different CD RW drives (I went and bought a new
drive to check that the error was not with the old HP.
I also have applied the latest ACPI patch (to get this machine to power
off correctly) - but I have tested without the patch and I still get the
same problem.

Any help would be appreciated. Let me know if you need any further
information.
