Message-ID: <4DC15DC8.2010302@mejor.pl> (raw)
Hello!
I'm hitted by issue described there:
http://lists.xensource.com/archives/html/xen-devel/2010-09/msg00164.html
. I'm using 32bit guest (no SMP) on 64 xen-server. On hardened-kernel
(grsec)-2.6.{35,36} there is silence in dmesg (i don't remember what was
going on on earlier kernels). On hardened-kernel-2.6.{37,38} and on
vanilla-kernel-2.6.{37,38,39} and git-sources-2.6.39_rc5-r7 problem exists.
Here is link to gentoo bugzilla entry: http://bugs.gentoo.org/358549 .
If any information could be usefull please let me know.
Thanks for help!
Marcin
