Subject: MMC Suspend Hang in kernel 2.6.32
Date: Thu, 10 Dec 2009 11:33:45 -0500 [thread overview]
Message-ID: <4B2122E9.1080109@sdgsystems.com> (raw)
Hi. I believe I'm running into the same problem that is reported here:
http://thread.gmane.org/gmane.linux.kernel/884017
It looks like the patch that helped the original poster got into 2.6.32,
but I still get the hang on suspend. I've tracked it down to the
bdi_wait_on_work_clear() function in fs/fs-writeback.c. I put a
backtrace dump in that function, and it's included below. This is on a
PXA320 device, but as far as I can tell, it's not caused by pxamci.c.
