EIPs may not be accurate as I had to recompile kernel-rt because what's currently in KOTD is overly fat due to CONFIG_DEBUG_INFO=y. -- 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.

Should have left it at 2.6.25/26.
Jan, as you know 2.6.27 got skipped by the upstream RT-patch series. AFAIK, kernel-rt wasn't part of openSUSE 11.1. I sent a request to Jan Blunck to create Kernel:RT in OSBS, yesterday. (This might get delayed due to holidays) If you're looking for 2.6.26 RT kernel, please try the KOTD "slert" branch. Could you try to reproduce the issue on the 2.6.26 RT kernel from the "slert" branch? -- 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.

I hope to have more time for 2.6.27 RT after the new year.

Jan, i guess at least the request (comment 3) regarding providing a stable RT kernel got full filled (based on the .26 RT upstream patch-series now). Thanks for your interested in the openSUSE RT kernel. Your contribution and feedback is more then appreciated! Sven, how should we proceed with this bug? Should we try to reproduce this on 2.6.26? Or is this a 2.6.27-only thing? -- 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.

IMHO, any efforts should be concentrated on the new -rt git tree Steven Rostedt pushed out a while ago. -- 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.
