I have the unusual scenario of processes hanging and becoming unkilling here. Not only are they unkillable, but each of them absorb as much CPU time as they can. If not for the kernel-premption patch, I'd probably be deadlocked. Most of the processes are 'sh' and 'make' from a compile job, but 1 is 'stonerview', an xscreensaver hack.
I got the output of Alt+SysRq+T, and examined a few of the tasks that had hung. Interestingly enough, all three of them have several lines in common (the full traces for 3 processes are at the bottom, I can provide more if they're needed). The common lines are as follows:
Trace; c01233f1 <check_pgt_cache+11/20> Trace; c01234ca <clear_page_tables+ca/d0> Trace; c01261b6 <exit_mmap+126/130> Trace; c0114876 <mmput+66/80> Trace; c0119266 <do_exit+a6/240>
Any idea as to what may be causing this? This is an AMD Athlon 900MHz, memory known to be good, running Linus kernel 2.4.12 along with preempt-patch and ext3-0.9.10. Since it seems at least remotely possible that one of these patches is causing the problem, I'm cc'ing those maintainers as well. -- -Steven In a time of universal deceit, telling the truth is a revolutionary act. -- George Orwell Freedom is slavery.
