Manny/May,

I don't really know how to figure out which oops is which yet (in spite
of Andy grilling me). ;-)

Please look at defects 23257 and 23034, and try and figure out if the
oops you hit is the same as one of these, then update the defect.

Thanks,
John

Dude, you have to get your kernel oopses correct!
This is another example of

TED00023034 - kernel crash: DBE in yenta_irq during shutdown

As far as I know no one has seen another example of
this bug where we got a page fault while trying to write
a core file.

Your clues are that at the top of the stack trace it says:

[<ffffffff8218afe4>] yenta_interrupt+0x14/0x118

and somewhere underneath that is a line similar to

[<ffffffff82195fdc>] mgmtbus_hard_start_xmit+0x11c/0x188

The actual numbers may change, but the function names,
yenta_interrupt and mgmtbus_hard_start_xmit will stay the same.
