Hello all:
I was getting a reproducible crash during an update of a xen system. The problem went away after I set SELinux to permissive, but the fact that it crashed was alarming (first one on a non-dev system that I've had in over a year). I attempted the update earlier but it crashed at the same point after attempting to update selinux. After verifying hardware (all clean) I ran it again and crashed in the same location. Third time failed again in same location. I rebooted, changed selinux, then it completed after that. Unfortunately there are no dumps and I had to put the system back into operation. Didn't see anything in bugzilla either. Anyone else seen this?
