They seem fairly regular but for some reason more often than not don't end
up in the log, this is the only one I have so far.

I've tried a serial dongle but I can't seem to get the kernel parameter to
set the speed.
I have:
 console=ttyUSB0,9600n8r console=tty

And without it I can use minicom to test and the port works fine with it I
just get some garbage... Any ideas? I've also built in usb and the usb
dongle support (i.e. not a module).

Would it be worth my time typing in a transcript? It looks quite a lot to
type and would be error prone :( but if another trace would make the
difference. I'd give it a go.

Thanks,
M

hm, capturing oopses over USB is likely to be problematic - there's a
heck of a lot of software involved :(  I've never tried it.

Cellphone photographs work well.

Good news, though memtest86 wasn't showing any errors I tried my laptop 
with some other memory and it's working fine now even the graphics 
problems have gone away.
Sorry to trouble you with these reports, many thanks for the advice.

Not quite sure why the memory isn't failing the test program but I'll 
try a few more things...

OK the memtest86+ test ran for over 12 hours with no problem.
I then booted and as luck would have it got another stack trace in the
logs, please find attached.

Curiously it seems to happen under light load sometime when just browsing
the RC releases could easily be triggered with find -type f |xargs cat >
dev null but that isn't the case now.

Thanks,

I have no stability issues with the old debian 2.6.31.6 kernel.

I have run the memtest86 before with no issues, I will run it over night
tonight, I had considered this.

I've run a few newer kernels on this machine but I was trying some new
code from debain testing and the 2.6.36rc5 kernel was the first that
started the filesystem errors:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599118
There is another different panic attached:
http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=kern.log;att=1;bug=599118

The kernel before that was  2.6.34-1 (again a debian release) which was
stable except for the intel graphics driver but that's another problem and
I'm not alone there... In fact it was the graphics driver that was my
reason for running the memory test, that is somewhat improved do to a
patch but I get these filesystem panics before the graphics driver dies
now... :(

I'll do some memory testing.

Will everyone be OK with screen shots if the memory test is OK and I
capture some more.

Thanks,
M

I assume from the subject that you do NOT have crashes on some other kernel version that you are running?  It isn't really clear from your email.  Otherwise, the first suspect in frequent and mysterious crashes is bad RAM, and running memtest86 for a couple of days is the recommended course of action.
