Wow, the stack and registers are pretty trashed at this point with 0x30 all over
the place. 0x30 happens to be the ascii for '0' (zero). Not really helpful, but
it shows that it isn't just random data being tossed around in memory.

I think the second crash in pdflush is unreliable.

Since this occured shortly after the ACPI error, which was followed by a spew of
NULL's to printk(kernlog), it seems reasonable to me that the initial problem is
somewhere in or after the ACPI error handler. Hell, it may even be a bios bug.

Is this reproducible? Does it still occur if you boot with acpi disabled?
