PowerWave 604e/180, 2.0+0.5GB disk, 64MB mem. Userspace as of Jun 4 or so, Kernel as of Jun 7.
System: NetBSD powerpc 1.5W NetBSD 1.5W (POWERMAC) #0: Thu Jun 7 22:00:24 CDT 2001 root@powerpc:/usr/src/sys/arch/macppc/compile/POWERMAC macppc
trap type 300 at 14c620
Stopped in pid 1017 (make) at vgonel+0xd0: lwz r9, r11, 0x64,
After rebooting, I ended up with a new panic:
panic: kernel diagnostic assertion "umap->refcount != 0" failed: file "../../../../uvm/uvm_bio.c", line 236
I've only had the second crash once, while the other one has reoccurred a few times.
The system ran fine with 1.5.1-BETA2 while I was compiling and installing -current,
which makes me suspect the new powerpc pmap or other recent change.
I've been able to reproduce the problem by doing various compiles. Sometimes
it takes a while for it to happen, at other times not. First occurrance was
while compiling the nbench pkg. I've only had the second panic above one.
If anyone needs console/debugger access to debug this, let me know.
I haven't debugged the problem.
