Description sla Lom 2008-11-09 17:42:35 UTC 
Hello There 
First time submitting a bug so forgive me if i did not follow rules fro this process. 
This but is notices in 2 different server/ mother boards same vendor ASUS 
1) p5E /  90  nm  Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz / 8G RAM 
4 x 500G disk 

2 ) RS120 E5/ 45 nm Intel(R) Core(TM)2 Quad  CPU   Q9550  @ 2.83GHz / 8 G Ram 
1X 500 1 X 1000G 


Os on both server:
doom0  2.6.25.16-0.1-xen #1 SMP 2008-08-21 00:34:25 +0200 x86_64 x86_64 x86_64 GNU/Linux  
In the case server 2 kernel is recompiled, just with option pcipassthrough in the XEN doom0 options and has this options enabled as kernel internal / not a module . but 1rst serer has original kernel 

also both machines have 3 4 vgs like

The workaround so far is to stop and start xend 
AS a result of this  no shutdown is working 
and the system is acumulation  Wainting on io .. 
I have a server that is alreadt is 74 % waiting on io (2 ) and i cannot just reboot since it is remotely colocated. 
I also kept the old kernel 2.6.25.11-0.1 and does  not have this problem 


One more think the filsytems are resiserfs.

after i have executed the workaround all my lvm is locked 
cannot crate an logical volume 
shutdown if not working 

Please help
