Roland,
Occasionally, I see:
attached to 1717 = 0xde089000
utrace_control: -EINPROGRESS
pid 1717 reports quiesced to 0xde089000
BUG: sleeping function called from invalid context at kernel/sched.c:5428
in_atomic():0, irqs_disabled():1
no locks held by uttest/1717.
irq event stamp: 1396

Thanks for the report, Ananth.
Ah! The i386 will enter do_notify_resume() with interrupts disabled.
Other machines don't do this (x86-64 and powerpc64, anyway). It is often
harmless, because if TIF_SIGPENDING is set, we'll first enter
get_signal_to_deliver() and implicitly reenable interrupts
