Further tests revealed that the problem has not gone away completely  
(although it seems to be happening more sporadically).
If Mini-OS does not initialise XenBus (if you remove xenbus_init()  
call from kernel.c) the problem will not appear at all. So far I have  
not been able to pinpoint the root cause of the problem though. Maybe  
somebody more familiar with XenStore will be able to help.
The patch certainly does not break anything though (this is mostly  
for Keir's attention).
I'll get back to you if I find anything more.

Cheers
Gregor
