That would explain why the state of play of the interrupts is in an
unexpected state in the crash I reported:
"The point of failure in the panic was:
fs/buffer.c:1257
static inline void check_irqs_on(void)
{
#ifdef irqs_disabled
BUG_ON(irqs_disabled());
#endif
}
"
This is all new to me so I'm still at the head-scratching stage.
Ah, I see.
Thank you,
David,
Does the above make sense to you? Have you managed to reproduce the
crash I get?
Cheers,

I have easily produced a crash although it doesn't look to me like the
same one. I'm getting a NULL pointer dereference. The PMU stuff (used
by perf record|stat -e) should be quite independent of kprobes though.

Oops, never mind the above bit. I see this is not PMU-related, but use
of kprobes through perf. My bad.
