All,
I've got a quick question about the stack trace below. I see the flags <IRQ>
and <EOI> in this trace and would like to understand better what this means.
My swag is that it's showing that the stack trace is running in interrupt
context when the kernel panic'd.
Anyway, thanks in advance for the help ...
Cheers,
