After recent Xen client updates over the last couple of days, to

under high-load (e.g. a src build) the client is fairly frequently, but randomly locking up. THe only notice I have is that my SSH session to the VPS simply disconnects ... no errors in the shell, or in system message. @ the attached admin Serial console I see only the sudden onest of,

and then it just loops/repeats continuously, requiring a hard-restart of the VPS to get out of the loop, and recover.

Without knowing the context of those lockups, it's very hard to tell anything.

Guest boot config is unchanged, and quite simple

cat /boot/grub/menu.lst default 0 timeout 1 title PVGRUB root (hd0) kernel /boot/vmlinuz-xen root=/dev/xvdc noresume xencons=hvc0 kbdtype=us text nofb selinux=0 apparmor=0 edd=off noshell showopts splash=verbose initrd /boot/initrd-xen

Appears to be a frequent xen-related issue

with not much conclusive resolution.

See bug 768714 for pretty clear indication that this is also an issue without Xen involved. Where the problem stems from requires - as said above - at least seeing more that the bare "soft lockup" messages. And as with any suspected regressions, specifying just _to_ which package versions you updated, and not at the same time also _from_ which ones is also at best half helpful.
