Very Computer

Hello,

I have a problem with my Linux system. It is based on a Debian 1.3.1
distribution, although I built a 2.0.30 kernel specifically tailored for

my machine. However, I've experimented four system crashes that wreak
havoc
with the file systems.

The disk and IDE chipset characteristics are (according to Linux):

ide: i82371 PIIX (Triton) on PCI bus 0 function 57.
        ide0: BM-DMA at 0xf000-0xf007
hda: Conner Peripherals 1080 MB - CFS1081A, 1032 MB w/0KB Cache, LBA,
CHS=524/64/63
ide0 at 0x1f0-0x1f7, 0x3f6 on irq 14.

First I receive several console messages, from the
hard disk driver, warning that something is wrong with the disk:

=====================================================================
hda: read_intr: status=0x59 {DriveReady SeekComplete DataRequest Error}
hda: read_intr: error=0x40 {Uncorrectable Error}, LBAsect=2075232,
sector = 30945
end_request: I/O Error, dev 03:08, sector 30945

hda: irq timeout: status=0xd0 {Busy}
ide0: reset: success

hda: write_intr: status=0x51 {DriveReady, Seek Complete Error }
hda: write_intr: error=0x10 {SectorIdNotFound}, LBA sect=2067428,
sector=23140
hda: status error: status=0x59 {DriveReady SeekComplete DataRequest
Error}

hda: no DRQ after issuing WRITE
ide0: reset: success
hda: irq timeout: status=0xd0 {Busy}
====================================================================

Some days later, the showdown:

EXT2-fs warning (device 03:05): ext2.free.blocks: bit already cleared
for block 17
EXT2-fs warning (device 03:05): ext2.free.blocks: bit already cleared
for block 2046
EXT2-fs warning (device 03:05): ext2.free.blocks: bit already cleared

EXT2-fs warning (device 03:05): ext2.free.blocks: bit already cleared

EXT2-fs error (device 03:05): ext2_free_blocks: freeing blocks not in
datazone - block=12304384,count=1

kernel panic: EXT2-fs panic (device 03:05: load_block_bitmap:
block_group >= groups_count - block_group=524287, group_counts=13
======================================================================================

The kernel crashed leaving all the linux partitions unusable. I tried to
fix them using fsck but it wasn't possible, at all.

I've tried to find an explanation but my knowledge of the kernel is
limited so I've not been able to get to a conclusion. I suspect that
maybe the problem lies on the hardware but I'm not sure.

I'm very active, in my work environment, promoting Linux as a very
serious
alternative to other operating systems so I need to prove that the
crashes
are not Linux's fault. If someone has any idea I'd be very grateful for
his/her help.

Thanks in advance.

A friend of mine recently had undergone a similiar situation with his IDE
setup. We have been running 2.0.30 for a long time w/no problems like the
above. It eventually turned out (after going through, IIRC, 3 HDs, the IDE
controller going belly-up.  You may want to chenck that out. I don't know
what you did to your kernel, so I can't comment on that.

Seagate's and Quantums no problem, ive had a number of each under Linux
but the Connors ive tried ive had major problems with..

I presently running my Linux setup on a Quantum Bigfoot CT 4.3gig
no problems with it so far...

as to fixng your problem, im not sure how, i managed to go sideways around
the problem using a ISA I/O board, but speed and performance dropped way out :)

Laugh and the world laughs with you.  Cry, and someone yells, "Shut up!"

It is either the drive or the controller starting to die.

In more than 90% the problem is heat related!!!

Simply the drive-electronics ore/and the controler chip is getting too
hot. :-(

This *may* (just) work under windoze and dos, since with these
operating systems, the drives are just sitting there, not beeing accessed
most of the time.

This is different with operating systems like Linux, Unix, NT. Those *do*
put a lot more stress onto your drives.

Try to improve the cooling!

You don't overclock anything, do you?

Does a kernel compile give you SIG 11s as well?
If so, it may also be bad cache, bad memory, too agressive BIOS settings.

One last thing:
Have a look at hdparm and play with the settings a little bit.
Some EIDE features give problems with certain drives and/or controler-
(combinations). See the docs that come with it, as well as the source
of ide.c within the kernel sources for more information on this.

Good Luck and Regards,
Friedhelm
