Kernel Printing Warnings

Postby tjh » Mon May 04, 2009 3:44 am

Hi,

I'm getting the following warnings printed in my logs quite often, but only when I'm running KVM's. I'm running 9 KVMs, 8 FreeBSD 4.x based ones and a Windows 2003 Server based one.

Kernel is 2.6.29.2 with grsecurity-2.1.14-2.6.29.2-200905011803.patch applied.

System.map and .config are here: http://fozzie.muppetz.com/info.tar.bz2

I don't get this when I'm using vanilla 2.6.29.2

If it helps, I'm using KVM-85

Thanks,
Tim

Hi Tim,

I believe that was due to a mismerge on my part when porting to 2.6.29.2. It should be fixed in the latest test patch; let me know if you still have any problems.
