[zsh:945] I noticed that the Fedora bugzilla reports a patch that isn't present in OS 11.2, 11.3 or 11.4, so I'm just switching a test system over to an 11.3 kernel with this included. Reproducible: Sometimes Steps to Reproduce: Large amounts of NFS traffic but not always reproducible. Have seen this with both Broadcom and Intel Gbit Enet cards. Actual Results: See Details Expected Results: I/O should continue to run, processor should not lock -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The patch mention in the redhat bugzilla was committed to the 11.4 kernel about 1 month ago but I don't think there has been an update released since then. I have just committed the same fix to 11.3. They should both be in the 'kotd' kernel in a day or so. It looks very likely that the patch you found (thanks!) will address your problem. I propose that we leave the bug open for 2 weeks. If the problem recurs we will look deeper than. If it doesn't we can close the bug an assume it is fixed. Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
