i've dug through the system logs, but didn't find any explicity mentions
of a "kernel oops" (i've been wondering - what the heck *is* a "kernel
oops"?), but i've decided to include some of the errors and warnings i
did find in there. most of these probly have nothing at all to do with
the problem i describe, but i'll list them in what i think is their
order of relevance (if, indeed, they have any - if they don't, i'll post
some more pertinent ones as soon as it happens again):
Kernel Startup Log:
(ok, i have a spurios interrupt ... but apparently, these are nothing to
worry about?)
PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.
spurious 8259A interrupt: IRQ7.
