Like other people I have been experiencing random lockups when using the
latest development kernels.
2.1.97 does not lock completely so I managed to do a bit of detective
work and came up with the following.
running top shows the locked processes as having a state of 'D' (
uninterruptable sleep ) at kernel function __down_failed. And indeed the
process is unkillable.
This code is part of semaphores - I don't know enough about the way
semaphores work to debug any further.
The process then takes up system time ( it adds 1 to the system load )
and just sits there :-(
The processes can lock at any time, I've had init, syslogd and others
lock for no apparent reason, but the more processes that are running the
less likely the system is to lock?
Hope this helps
