Subject: rt61pci: oops in rt2x00lib_txdone(), entry->skb is NULL
Date: Tue, 07 Sep 2010 19:30:12 -0400	[thread overview]
Message-ID: <1283902212.5071.11.camel@mj> (raw)

Hello!

wireless-testing.git as of yesterday has a problem with rt61pci.  After
a minute of web browsing, the kernel reports an oops in
rt2x00lib_txdone() and no more traffic goes through.  That system used
to run a month old wireless-testing.git identified as 2.6.35-rc6-wl, and
it didn't have that problem.

The oops happens on this line:
enum data_queue_qid qid = skb_get_queue_mapping(entry->skb);

When it happens, entry->skb is NULL.  I cannot reproduce the problem by
ping, even by flood ping, but using a web browser on a moderately
complex site (e.g. cnn.com) triggers the oops reliably within a minute
or so.

The architecture is x86_64, it's a multicore system, SMP is enabled in
the kernel.

If there are no good ideas what it might be, I'll try to find time to
bisect the bug.

Pavel Roskin
