Subject: BUG: scheduling while atomic 2.6.39-rc7 (iwl3945_irq_tasklet)
Date: Fri, 13 May 2011 21:34:49 +0100 [thread overview]
Message-ID: <20110513203448.GA3523@gandalf> (raw)
Hi,
On 2.6.39-rc7 I've seen a panic due to "BUG: scheduling while atomic"
with the backtrace below (not much detail as it was written in a text
message while it was displayed on the screen!). All worked fine in
2.6.38.
This was soon after resuming from suspend (enough time to unlock the
screen, but not much else). I think it was the same bug I saw in rc2 but
didn't have time to track down. I can probably get it to happen again if
more detail is needed. It doesn't happen every suspend (I think it had
survived a couple of suspend/resume cycles at this point).
I could bisect if necessary, but hopefully the backtrace will be enough
to see what's going on?
Cheers
James
