Subject: Panic: dma_map_area overflow 66 bytes on 3.7+
Date: Fri, 28 Dec 2012 20:05:09 +0100 [thread overview]
Message-ID: <201212282005.10812.tweek@tweek.dk> (raw)
Hi list,
Since the release of 3.7 my main computer has been panicking a couple of
times on both 3.7.0 and 3.7.1 because of a 'dma_map_area overflow xx bytes'.
Example screen shot:
http://www.tweek.dk/panic.jpg
I can reproduce it somewhat easily by visiting http://www.openstreetmap.org/
and zoom erratically with the scroll-button on the mouse.
The panic seems to occur on line 229 of arch/x86/kernel/amd_gart_64.c, and
reverting commit aee77e4accbeb2c86b1d294cd84fec4a12dde3bd (r8169: use
unlimited DMA burst for TX) seems to fix the problem for me (at least I've
not been able to make it panic as before (yet)).
