[Pkg-alsa-devel] Bug#354041: "Bad page state at free_hot_cold_page" kernel errors

Wed Feb 22 20:55:01 UTC 2006

Package: alsa-source
Version: 1.0.10-3
Severity: normal
Tags: patch

Lately, I kept getting these kinds of kernel errors:

Bad page state at free_hot_cold_page (in process 'amarokapp', page ffff810001d930c8)
flags:0x4000000000000414 mapping:0000000000000000 mapcount:0 count:0
Backtrace:

Call Trace:<ffffffff8014ed63>{bad_page+115} <ffffffff8014f16f>{free_hot_cold_page+127}

       <ffffffff8010e09f>{ptregscall_common+103}
Trying to fix it up, but a reboot is needed

It turns out this is caused by alsa doing some wrong
allocation/memmapping.  The problem, as well a a patch is described in
a thread on linux-kernel [1].  I've just tested the patch, and all the
errors indeed go away. 

Apparentyl, this is already fixed in the 1.0.11rc upstream series, but
please include the patch in the debian package if you make another
1.0.10 upload.

Thanks!
Bas.
