Subject: kernel NULL pointer dereference in pxa3xx_nand_probe
Date: Wed, 05 Jan 2011 12:43:21 +0100 [thread overview]
Message-ID: <1294227801.3996.62.camel@sven> (raw)
Hi,
I've tried upgrading the kernel for a PXA300 based device from 2.6.36.2
to 2.6.37 and now it crashes on boot. Looks like a regression in the
PXA3XX NAND code. Does anyone have a clue on what might be going wrong
or will I have to bisect this?
