after upgrading to xen-srouces-2.6.20-r6 I started to get the following messages at the system log: The message seems to retrun every minute and really fills up the log files.

Created attachment 146702 [details, diff] kernel patch to keep synchronize_irq() from spamming the logfile Redh*t has disappeared the aforementioned RPM from its archive. This bug surfaced for me when I replaced an Intel NIC attached to a domU with a 3Com NIC (the Intel NIC wouldn't work right when the domU was restarted; the entire machine had to be power-cycled). I found the patch somewhere and applied it against xen-sources-2.6.20-r6, and it fixed the problem for me.
Dropped version. Try .29 or .31 :)
