After 3 panics yesterday, I finally got one while not in X, so's I could
jot down the details. the system is an amd64 3200+ on an asus k8v, with 1G
ram and a single 120G sata HDD on the onboard Promise PDC20378 (ad4 on
ata2). There's an atapi CDRW on the primary (P)ATA connector, as slave.
It's acd0 on ata0. It runs at PIO4.
The usage scenario is each of the past 4 panics has been the same: dagrab
-a -d /dev/acd0. It doesn't seem to be correlated to heavy cpu loading or
other disk usage. Details of this last panic (as usual, text paraphrased,
but the numbers are exact):
fatal trap 12, page fault while in supervisor mode
cpuid = 0 apic = 0
fva = 0x20
fc = supervisor read, page not present
ip = 0x8:ffffffff8036b06c
sp = 0x10:ffffffffaa78cbb0
fp = 0x10:ffffff0000b1f000
cs = base 0x0 limit 0xfffff type 0x1b
DPL 0 pres 1 long 1 def32 0 gran 1
pef = interrupt enabled, resume, IOPL = 0
cp = 2 (g_event)
tn = 12
panic: page fault
cpuid = 0
uptime = 2d 13h (weird, i'm sure it paniced at least twice yesterday)
The system was last rebuilt december 15th,

ANy hints on how to track this down better?
