2.1.81 oops-like events

While I was running PINE, it stopped accepting keyboard input. Shortly
afterward, the console was spammed with repeating sequences of


ending with

Code: 8b 4a 04 85 c9 74 22 8b 5a 18 8b 02 84 01 8b 0a 85 c9 74 08
Aiee, killing interrupt handler
page fault from irq handler: 0002

This looks like an oops, but ksymoops wouldn't process it, maybe because
the beginning is missing (it scrolled off the screen). Here are some
extracts from the System.map:

c010a004 T ret_from_intr
c010bb40 t do_8259A_IRQ
c011b778 T do_bottom_half
c011bd38 T do_sysctl_strategy

Then I rebooted (command-control-power (just kidding)) and ran PINE again.
After a little while, I tried to leave from it. It started to close the
folder I was reading, but stopped and after a few seconds I saw a single:

[<c0113efa>] [<c01b2298>] [<c0111ad2>] [<c017b382>] [<c010a07e>]
[<e010bb40>] [<c010bd98>] [<c010bb40>]

Since ksymoops doesn't want to parse that either:

c0113e7c T __down
c01b2230 T csum_partial_copy
c0111a1c T do_page_fault
c017b35c T ide_set_handler
c010a04c t error_code
e010bb40 - not found
c010bd7c T do_IRQ
c010bb40 t do_8259A_IRQ

I have an Amptron PM-7400 motherboard and IDE hard drives. I think I'd
applied Keith Owens' collection of patches and commented out "SMP = 1,"
but I noticed the message "SMP motherboard not detected. Using dummy APIC
emulation." at boot time.
