This Oops happened with mutt as the only active user process.
I'd been using uhci for a while with test kernels, as usb-uhci had
been oopsing on first mouse use. However, with test12 I found a
problem with uhci:

so I switched back to usb-uhci
Those PCI messages are new with test 12 - the USB controller shares an
IRQ with an SB Live card. That hadn't caused a problem previously.

Once again we have these two symbols on the stack.
Anybody else, who thinks this might be related?
I've seen these two symbols on all ix86-Ooopses with no raid
involved.
Does anybody have an idea, why we always see these symbols there?
Is it an common bitmask? L6 (from arch/i386/head.S) is freed after boot AFAICS.
Regards
Ingo Oeser

Probably spurious. Remember that ix86 show stack prints anything that
looks like a kernel address, whether it is a real return address or
not, you can get false positives. kdb goes to a _lot_ more work to get
a more accurate backtrace and even that sometimes goes wrong. Always
assume that any address on an ix86 oops might be irrelevant.
In this case L6 is the return address from start_kernel. start_kernel
ends up calling cpu_idle. Everything above cpu_idle will be the
interrupt handler, ignore anything below cpu_idle.
