Re: v2.6.26-rc9: kernel BUG at kernel/sched.c:5858!

Ok, now I tested it on my laptop (sorry, no serial console :-)) and I
get a spinlock recursion.

Not reproduceable without my debugging patch and with Miao's?


Sorry for bad pics, but it's the best I can
do with the camera at hand:

some of the msg is cut off, see pic #1 instead)

Should I use Miao Xie's patch as well?

My debugging patch already includes it.

Ok, so this initial problem is reproduceable on your laptop? I did try
to get it on my dual-core laptop without success. Maybe you could send
me your config-spec (offline) and your test scripts?
Then we could stop crashing your PCs :-)



Thanks,


Vegard
