I'm having troubles with xm save. The command
/usr/lib/xen-3.2-1/bin/xc_save hangs forever
in read() system call.

I really have no idea of whats happening here
as the logs dont tell anything really except
that the vm guest itself says:

 PM: Device pcspkr failed to suspend: error -22
 xen suspend: device_suspend -22

This is what I get in the xend.log

 DEBUG (XendCheckpoint:91) [xc_save]: \
    /usr/lib/xen-3.2-1/bin/xc_save 25 2 0 0 0
 DEBUG (XendCheckpoint:344) suspend
 DEBUG (XendCheckpoint:94) In saveInputHandler suspend
 DEBUG (XendCheckpoint:96) Suspending 2 ...
 DEBUG (XendDomainInfo:467) XendDomainInfo.shutdown(suspend)
 DEBUG (XendDomainInfo:1092) XendDomainInfo.handleShutdownWatch
 DEBUG (XendDomainInfo:1092) XendDomainInfo.handleShutdownWatch

The host system is debian lenny with debian xen version 3.2-1.
The host kernel is homebaked from debian source 2.6.26-13.
Basically I stripped off all unnecessary modules (sound, etc)
and added ext4-7 patch. The host kernel is static.

Any ideas?
