Are you thinking of RHSA-2009:1472-1?  Comparison point, upgraded
several domU's on a box to 5.4 and halted/created them with no boot
issue.  Upgraded the dom0 later to 5.4 and also had no restart
problems.  So I have a couple of dom0's running a mix of 5.3 and 5.4
domU's (x86_64 and i386) with no problems.  The bug report does say,
"domU sometimes fails to reboot," so looks to be a circumstantial issue,
not a definite one.
