hints on wait queue bug?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi there,

I've got a problem where lots of io to the console seems
to break something in the kernel, resulting in a segfault,
along with a kernel error.

I dove into it, and found that it's related to wait queue
stuff.  I turned on the wait queue debugging, and got the
following, just prior to things going off the deep end.

bad magic 802ccb24 (should be 802ccb2c), kernel BUG at sched.c:729!

Is there some tutorial on this stuff somewhere (besides
reading the code -- I'm doing that now!)  

Has this stuff changed a great deal since 2.4.5 (when this
code last worked correctly)?

thanks,
rob
