I'm trying to update a amd64 dom0 to -current (to use dm(4)).

I've been unable to get xend to stay running. The python interperter
recives a SIGBUS (signal 10) and dumps core.

The kdump(1) shows interesting oddness:
245 8 python2.5 PSIG SIGBUS SIG_DFL: code=SI_USER sent by
pid=-87363552, uid=32639)
note the bogus pid and uid, these two values change to different
yet similar value from trace to trace.

I've tried xenkernel3/xentools3 with python25, and
with both python25 and python26. All these cases exhibit a similar
SIGBUS to xend.

I'm running 5.99.11, sources from about the 17th.

interesting. I'm running a amd64 5.99.11 kernel on a 5.0 userland, and
don't have issues ...

I'm running -current amd64 dom0/domu from May 5th with no issues. I'll
update my dev box today and report back tomorrow if nothing else crops
up in the meantime.

Sorry for the delay, I've struggled to get a cvs sync that isn't broken.

Built and running as of Fri May 22 11:29:03 EST 2009, all seems to be fine. I haven't updated userland ... yet. uname and package list below.

Just before updating I did see some vnds stay tied up when domu failed to honor 'shutdown -r now', shutting down completely and then being unable to start them back up. Bit of a pain ... I'll check if I replicate the problem with current.

The only thing that crosses my mind for your issue is that I seem to remember some xen related changes that required a userland of at least a specific vintage with a new kernel. I only mention it as I'm not sure from what version you are updating.
