Hi,
I seem to be getting some odd behavior that I think may be related to the preempt patch somehow.
Problem: --------
The machine completely hangs with the exception of constantly repeating the same 1/4 second sound sample that happens to be playing at the time of the hang. The kernel does not respond to network traffic, nor to SYS-REQ commands. A hard reset is all that works at this point.
CPU, Kernels and Patches: -------------------------
Dual Pentium III 450MHz, SMP Kernels
Stock 2.4.17+preempt+lock-break+mki-adapter+win4lin
- Problem extremely intermittent, maybe once a day.
Stock 2.4.18+preempt+mki-adapter+win4lin
- Very frequent, and also repeatable every time I try to start win4lin.
Stock 2.4.18+mki-adapter+win4lin
- No problems thus far. Win4lin works fine.
The mki-adapter and win4lin patches are needed for win4lin to work. I include them here because it seems to be some sort of interaction between them and preempt, or some behavior that they can evoke repeatable which causes the problem to surface.
The problem could easily be somewhere in the win4lin stuff, and preempt causes it to appear there.
What can I do to try to hunt down this problem, given that the machine is completly useless once it happens?
