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 Trace; c01234ca Trace; c01261b6 Trace; c0114876 Trace; c0119266 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.
