Hi,

I've got it booting.

The machine without boot problems reports the use of emulated TSC:

(XEN) TSC not marked as either constant or reliable, warp=575 (count=2)
(XEN) dom109: mode=0,ofs=0x417376aa9c8c,khz=2633032,inc=1,vtsc count:
3576850 kernel, 9534 user

The machine with problems reports no domains having emulated TSC:

(XEN) TSC has constant rate, deep Cstates possible, so not reliable, warp=0
(count=3)
(XEN) dom23: mode=0,ofs=0x41dc316839ac,khz=2208968,inc=1
(XEN) No domains have emulated TSC

I have nothing specified in the xl config for tsc_mode. If I set
tsc_mode='native'
and restart the DomU it boots without any problems.

If I explicitly specify any of the other tsc_mode it gets stuck with
jiffies not
incrementing as before.

Mark
