HI list!
We regularly experience kernel Ooops on our alpha SX164 with ext3 on md
on ide controller:
No modules loaded, lsmod empty, self compiled kernel
ksymoops 2.4.5 on alpha 2.4.25. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.25/ (default)
-m /boot/System.map-2.4.25 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

Can you help us with this oops and how to fix it?

Hi Ingo, hi Neil, hi lists!
We have some problems with the md code on alpha. We get regular oops
when using the md raid1. Here we got another oops when fsck (at boot
time) the raid:
This was after a fresh reboot. As long as only the raid is *not* mounted
of fsck the machine works without any oops.
I also can mount the hard disks *without* raid directly as hda1 and
hdc1, and do NOT get any errors here, so I suspect that only the md code
is the culprit.
Please tell me how I can track down this problem, how I can help you!
ksymoops 2.4.5 on alpha 2.4.25. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get

Please clarify symptoms regarding fsck at boot and Oops. Are they like mine?
Symptoms I have had with a compact flash boot hda (ide) are that
clean boot with fsck doing nothing is OK no Oops.
If fsck corrects anything and boot continues then Oops will occur. That is I
need to reboot machine after fsck rc=1 or I get Oops.

Ross.

Looks like the well known bad assembler code with gcc.
On the alpha you see the problem first in the
raid1_read_balance() code sequence..
You should use gcc 3.3.2 better 3.3.3.
For alpha find the binary rpms here:

Very likely.

Also, here is a hack (originally from Jay Estabrook) which
should work around a bug in older compilers.

I used this diff and it is working now, at least I hope, tests are
coming.
Again, thanks again for the fast answer!

I know from my own system, that the oops in the raid1 sources, are
not the only point, where gcc generates wrong assembler code.
So it't better not to workaround just this single point, but
use the fixed gcc instead.

I've found similar results with the unstable Debian 2.4.25.-1-686
kernel.

Same again here.
I have /dev/hda2 listed in raidtab as a failed disc, lilo points to hda
as boot. I get kernel panic when attemtpting to boot to it.
I thought this strange as I have another system running the very same
kernel (even used the same copied kernel deb) with a UU (no failed)raid
1 running off a hpt372 onboard controller (as soft md, not hardware raid
1). The raid device was present prior to the kernel in this instance.
I was impressed that the std initrd wokred with both md and hpt372
without modification, where the process had been more involved in the
past requiring a custom initrd or "compiled in" kernel.
I thought that the devfs (compiled in with the std debain kernel) may
have been an issue, but it has never been in the past and the same
filesystem on the raidtab listed "failed" drive /dev/hda2 is happy.
I can boot the the raid 1 as root filesystem when passing root=/dev/md0
loading through a system rescue disc (http://www.sysresccd.org/) with a
2.4.25 kernel.
Attempting to boot to /dev/md0 with the Debian 2.4.25-1-686 kernel
panics after attempting to mount the device /dev2/root2 as ext2, minix &
fat (possibly others that disappear before they can be read) and
complains the std way when you attempt to mount with the wrong fs.
...
pivot_root: no such file or directory
/sbin/init: 347: cannot open dev/console : no such file
Kernel panic: Attempted to kill init !
I've attempted to pre-load the initrd modules, but didn't expect this to
be a solution and it wasn't.
I'm scratching the head and losing hair...
Never had any trouble of this sort before.
Any suggestions appreciated.
Cheers,
Lewis

There is a patch by Ivan against the MD code which avoids
gcc3 < 3.3.3 from generating bad assembly code. This patch
is sitting now in the 2.4 BK tree.
Have you guys tried that one?

Lewis, dont know what is going wrong here for you. Sorry.
