I have a similar issue in dom0, running Xen 3.0.4 (installed from sources).

dom0 was not running any guest domain.
In fact, xend was even not running (I execute "/etc/init.d/xend start" manually
when I want to run Xen).

I removed about 20 rpm packages when this happened (rpm -e package1 package2
...).

The system was not responsive anymore - I couldn't switch between consoles
(ctrl + alt + F1 etc.). Magic SysRq keys were still working, and the system was
still responding to pings (I couldn't log in via SSH though).

This is what I grabbed from the screen, it can contain typos:

BUG: soft lockup detected on CPU#0!

Pid: 11, comm: kblockd/0
EIP: 0061:[<c0101227>] CPU: 0
EIP is at 0xc0101227
 EFLAGS: 00000246  Not tainted (2.6.16.33-xen #3)
EAX: 00030000 EBX: 00000000 ECX: 00000000 EDX: 00000000


If someone needs a full log, I can trigger the bug once again.
