Is there a way for me to do this from the above information? As I said in the
original message, I failed to get a crash dump after reboot (because, it turns
out, I hadn't set up my gmirror swap device properly). Alas, with the latest
panic, it appears to have hung[1] during the "Dumping" phase, so it looks like
I won't get a saved crash dump this time, either. :-(
Speaking of the latest panic, here it is:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x308
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff806026ef
stack pointer = 0x28:0xffffff8094acd2d0
frame pointer = 0x28:0xffffff8094acd350
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 20992 (df)
trap number = 12
panic: page fault
cpuid = 0

[1] Not quite hung solid: when I press the power button I get this appearing on
the console:
acpi0: suspend request ignored (not ready yet)
acpi0: request to enter state S5 failed (err 6)
