This is related to previous e-mail referred to in the header of this msg.
The previous msg contains my custom kernel and dmesg editted to show where the hang is.
I think this problem started showing up after Monday eve's CTM bucket before it went south, and it crashed again today after catching up with CTMs and doing makes on world & kernel.
It is with the 4BSD scheduler (ULE is broken for me as ref'd in another msg to this list).
The trap seems to spring when the system gets busy; with me it pops sometime during a 'make'.
I am having to use a kernel I built last week until this is fixed (thankful for backups, and yes the older kernel is what I must use to finish making these newer things ;) .
At the point of the crash, I hand-copied the following:
kernel trap 9 with interrupts disabled
Fatal trap 9: general protection fault while in kernel mode
instruction pointer = 0x8:0xc07a6c7d
stack pointer = 0x10:0xd2797bce
frame pointer = 0x10:0xd2797bea
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 28 (swi8: tty:sio clock)
kernel: type 9 trap, code=0
Stopped at atpic_handle_intr+0x4d: cmpl $0,0x4(%edi)
db> trace

(null)(6b00646e,73637274,62690077,5f327363,70726770) at 0x26c4

Again, if someone could help or give me a tip or two, I'd appreciate it.
I will need to continue this next Monday (I don't have any li'l-endians at home ;) .
Thank you,
