Hiroshi-san's patch for 2.6.24.3-29.el5rt kernel
Attaching Hiroshi-san's patch for 2.6.24.3-29.el5rt kernel.
------- Comment From matthewclarke.com 2008-03-20 11:32 EDT------- Peter has installed the new patch '2.6.24.3-29.el5rt.42841' on 3 of our machines. We ran multiple stress tests on the load that we knew use to cause the kernel panic, and after 50 iterations no failures were seen. A substantial run of stess tests have been submitted for a weekend run -> http://jsvtaxxon.hursley.ibm.com/build_info.php?build_id=19111 to see how it copes. This looks like the kernel patch has fixed the system hangs that we have been seeing. ------- Comment From jstultz.com 2008-03-20 19:50 EDT------- Clark: Please pick up hiroshi-san's patch for MRG. ------- Comment From paul_thwaite.com 2008-03-25 06:35 EDT------- Load Level tests have been running all weekend and no failures have been seen so far. All 5 minute tests have passed. 50% of 1 hour tests have passed. The 3 hour tests are yet to run. We have 3 machines currently running these tests so it will take a while to get through them all. The fix does look good. Fix picked up with the 2.6.24.4 stable patch which should be rolled out this week. I'll change status to MODIFIED and if we're all happy we can close it next week. Clark ------- Comment From sripathi.com 2008-03-26 01:28 EDT------- Yes, from IBM's side we are happy about the fix. ------- Comment From sripathi.com 2008-04-02 12:08 EDT------- Verified that the patch is in 2.6.24.4-30.el5rt kernel. |
