Oops, forgot the PC from the panic:

Hello all,
I'm suffering from sporadic hangs on a Powerbook G4 running 10.3.9. Unfortunately they first appeared shortly after two events:
1) The combined "Java for Mac OS X 10.3, Update 5", "Security Update 2007-002", and "Daylight Saving Time Update" updates in mid-February.
2) The failure and subsequent replacement of my PB's logic board.
The system would simply freeze, mouse input and all, and I'd get no panic dump on screen, not even the "pretty" one. Since then I've enable panic dumps (nvram boot-args="debug=0xd04"). Nothing gets written in /Library/Logs/panic.log or /cores, but from what I jotted down from the screen at the time it occurs + gdb, I get the following:
Unresolved kernel trap: 0x300 - Data access
DAR: 0x0000000C
MSR: 0x9030
DSISR: 0x40000000
XCP: 0xC
backtrace:
0x642d8 <vm_map_lookup_locked+152>: cmpwi cr7,r3,0
0x58998 <vm_fault+364>: mr. r29,r3
0x910fc <trap+2456>: mr. r22,r3
0x9402c <thandler+204>: lis r10,512
There are no kernel modules on the backtrace.
So, my two questions:
1) I doubt many are still on Panther, but has anyone else seen this problem? Could it possibly be a bug from the updates? I don't think mach_kernel was touched by them...
2) Could this be a hardware issue? (shoddy repair work? RAM going bad?) It passes the TechTool memory test every time...
Any other suggestions on how to debug further are appreciated. I don't have a second Mac, so hooking up the kernel debugger won't be easy.
Thanks,
- Mike
