Hi Jeff,
just recompiled the kernel with all debug flags (GENERIC default). Now I
get a page fault instead of the spin lock timeout. However, it does not
produce a dump for dumpon/savecore right now and I don't have serial
cable handy. I will get a serial cable tomorrow to grap the db> output
(hopefully). Or is there a way to put the screen output into a file?
ldd on kqemu.ko doesn't output anything.
However, when I recompile kqemu port with CFLAGS+= -DKSE it works then
with a patched SHED_ULE (SHED_SMP). But thats not the point. Attilio
provided a kqemu.diff that is supposed to let kqemu work without setting
-DKSE. With the "old" SHED_ULE this patch worked well and does not crash
(kqemu compiled without KSE).
Expect the kqemu issue, "it works under x86".
Greetings,
Stephan
