Hello,

Sorry for not responding to this earlier; I’ve just gotten back from
parental leave.

If you’re still having issues, please submit this report to
xen-devel@lists.xenproject.org .

Thanks,
 -George

I'm afraid the above is too little information to do anything about it.
It's also not clear whether what's seen above is all that was visible
to George when he suggested to submit the report here. Please supply
all technical information you've collected so far in the context of
this issue. This being a "mobile workstation" (whatever exactly this
means; some quick googling suggests a laptop) may imply you have no
option to make use of a serial console, which may make debugging of
this issue more complicated. Please clarify this aspect.

Please also consult Xen's command line documentation [1] and see
whether making use of one of the "reboot=" sub-options would help you
get around the issue. If one helps, please also report back here.

Additionally I'm afraid I can't make sense of "Is there a way to edit
the boot file?" What "boot file" are you talking about?
