[Xen-devel] Xenwatch crash on migration

[Nathan March <nathan@xxxxxx>]

Running into an intermittant issue where the domU xenwatch thread gets 
stuck in D mode on migration:
root        17  0.0  0.0      0     0 ?        D    Sep13   0:00  \_ 
[xenwatch]
It was in S before attempting the migration and once it goes into D the 
only option is to destroy the VM.
Dom0 - xen 4.1.1, kernel 3.0.3
Domu - kernel 2.6.32.27, 64bit pvops

Haven't found any indication of an error anywhere, not sure how to debug 
further since I can't attach to the thread with anything.
Possibly related to "xen/pv-on-hvm kexec: prevent crash in 
xenwatch_thread() when stale watch events arrive"?
- Nathan
