>Description:
I've been experiencing regular kernel panics on 6.3-RELEASE machine.
This machine was previously stable under 6.2-RELEASE.
The crashes are always in the sis0 driver.
The first crash I was able to capture looked like this:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0xbfe7a7e8
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc07f8a16
stack pointer = 0x28:0xe6704c20
frame pointer = 0x28:0xe6704c68
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 31 (irq19: sis0)
trap number = 12
panic: page fault
cpuid = 0
Uptime: 59m55s

The subsequent two captures looked like this:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x40
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc07f9bec

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 31 (irq19: sis0)

The final crash was different... It hung the machine completely.
I'm not sure if the hang was related to the crash, or whether it
was background_fsck hanging the machine. I've had some problems
with background_fsck in the past.

Although I have had several dumps to $dumpdev, savecore has
never been able to retrieve any of them!! So, i can't provide a
backtrace at this time. I'm attempting to deduce why savecore
never produces anything..
savecore: error reading last dump header at offset 4296851456 in /dev/ad0s2b: Input/output error

>How-To-Repeat:
The panic occurs most often when the system is under high load.
"/usr/src# make cleandir" can cause the problem. Also, it is more
likely to happen during gmirror re-builds (which are common due to
all the crashes).
However, it has also crashed a couple times under low load.
