2.6.34-rc2: xen DomU not booting

Hi there,

again a bit late in the game, I tried to upgrade one of my DomUs from
2.6.33 to 2.6.34-git (tried -rc1 yesterday, pulled again today, so I'm on
-rc2 now):

------
dom0# xm create sid.cfg -c
Using config file "/etc/xen/sid.cfg".
Started domain sid

------

Then it just "hangs" there: it won't return to the shellprompt (as if the
domU crashed) but it won't connect to the domU console either (as it does
perfectly with 2.6.33). And indeed, the domU is listed as running:

dom0# (xm list sid ; sleep 3; xm list sid) | grep ^sid
sid 55 256 1 r----- 140.8
sid 55 256 1 r----- 144.3

Also, "xm dmesg" is blank and netconsole doesn't work inside a domU, IIRC.

Hints how to debug this (besides doing git bisect, again) are very much
welcome!

Oh, the Dom0 is Ubuntu 8.04 (2.6.24-24, Xen 3.2.0) on a Mac Mini.

Thanks,
Christian.
