I hate following up my own post, but I manages to get some significant
information.
The console (previously inaccessible after the crash) was "on screen"
for the last event and I get the the following:
FAILURE - malloc ATA request failed
cannot allocate ATAPI/CAM request
(cd0:ata1:0:0:0): out of memory, freezing queue.
FAILURE - malloc ATA request failed
ad0: FAILURE - out of memory in start
(These two lines repeat 15 times)
panic: kmem_malloc(4096): kmem_map too small: 216326144 total allocated
Debuggger("panic")
Stopped at Debugger+0x54: xchgl %ebx,in_Debugger.0
So it looks like in need to tune my kernel a bit.
Will this work?
options VM_KMEM_SIZE_SCALE="4"
options VM_KMEM_SIZE_MAX="(1024*1024*1024)"
options KVA_PAGES=512
I found these suggested in a prior thread, but I am uncertain if the
values are even close to appropriate to my system (no PAE, UP, 384 MB
RAM).
