*******************************************
It stops responding at all as 3 days ago.
Just the same picture :-

PV DomU CentOS 5.2 has been tested with new kernel
During
shutdown mentioned DomU usual sequence of daemon's
messages drops into stack trace with following messages at the end:-

xenbus_dev_shutdown:   device/vif/0 timeout closing device
xenbus_dev_shutdown:   device/vbd/51712 timeout closing device
System halted.

Jeremy,

Bellow follows my message to you sent on 3/14/09
The bug is old. 
I do have null modem cable ( 2 m.) . Setting up serial is quite possible,
but not right now. Boxes are located in different places.

Two PV DomUs (CentOS 5.2 , F10) have been tested with new kernel
During shutdown of any one of mentioned DomUs usual sequence of daemon's messages drops into stack trace with following messages at the end:-

xenbus_dev_shutdown:   device/vif/0 timeout closing device
xenbus_dev_shutdown:   device/vbd/51712 timeout closing device
System halted.

After that Xen Host stop responding at all, just dies.

Boris

Change fef20d9c1380f04ba9492d6463148db07b413708, "vsprintf: unify the
format decoding layer for its 3 users", causes a regression in xenbus which
results in no devices getting attached to a new domain.  Reverting
fef20d9c1380f04ba9492d6463148db07b413708 and
39e874f8afbdb3745e2406ce4ecbde9ac4cbaa78 fixes the problem.

I haven't identified what format string is being handled wrongly, so I
don't know what the precise bug is.  The most complex looking format in use
seems to be %.*s; there's also "%s/%s", "%i" and
"%lX".
