IO errors on dom0 with 2.6.32.x kernel compiled from git

[lists]

 Hi guys,

 I'm not 100% I'm correct, but I thought i would ask here anyways.

 At first I noticed the guests on my Xen server were no longer reachable 
 by SSH.
 Luckily my dom0 still was so i logged in to see what was wrong.

 No matter what i did, I kept bumping into "Input/output error" 
 messages..

 A hard reset was the only option, and everything came up just fine, and 
 is working again. This is why I suspect some kind of bug with the git 
 xen 2.6.32.x kernel, which is why I'm asking here if anyone has a clue 
 or maybe encountered the same thing before, or - a man can hope - just 
 fixed a similar issue in that kernel ;)

 The server had been online for 6 days, running 6 guests without any of 
 them being very loaded. Running Xen 4.0.1, kernel 2.6.32.27, XFS 
 filesystems.

 A git pull updated my currently in use code to this:

 75cc13f..3d14ce7  xen/stable-2.6.32.x -> origin/xen/stable-2.6.32.x

 Any pointers will be very much appreciated!

 Kind regards,

 Bart Verwilst

Oh, XFS filesystems. That is an oddity. Do the guest of yours
that don't have XFS run fine?
