Comment 1 Michal Schmidt 2007-03-29 12:02:51 UTC
I've checked the patch proposed in attachment #151181 fixes the bug.
Comment 2 RHEL Product and Program Management 2007-03-29 21:46:03 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.
Comment 3 Michal Schmidt 2007-04-06 10:04:40 UTC
Update: The fix is incomplete. I was able to trigger slab corruption with it. Upstream has fixed it with a series of 4 patches from Hugh Dickins ("holepunch: ...", git commit 90ed52ebe48181d3c5427b3bd1d24f659e7575ad). These seem to work reliably.
Comment 4 RHEL Product and Program Management 2007-04-17 19:22:11 UTC
This request was evaluated by Red Hat Kernel Team for inclusion in a Red Hat Enterprise Linux maintenance release, and has moved to bugzilla status POST.
Comment 5 Don Zickus 2007-06-12 18:47:06 UTC
in 2.6.18-24.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5
Comment 6 Michal Schmidt 2007-06-22 18:49:37 UTC
I tested 2.6.18-27.el5 and ran the testcase for 6 hours. The bug is fixed.
Comment 8 Mike Gahagan 2007-09-20 15:17:51 UTC
testcase has run overnight on one of my test systems, no issues so far.
Comment 9 Dave Fogarty 2007-09-28 23:56:06 UTC
What is the status of this bug? Is an official RHEL5 kernel available? We are actually seeing this in the wild and would like it to stop.
