Is this reproducible? (In reply to comment #2) > Is this reproducible? I am trying to reproduce this bug with autotest, hope it will have a result tomorrow.

If you can reproduce it verify that it is still reproducible 1) with ksm disabled, 2) without usb tablet. Note: check only 1 or 2 not both simultaneously.

Hi, Gleb, I am trying to reproduce this problem as your advice, but seems it will take a little more time, it's hard to reproduce. Hi, I tried to boot RHEL4.9 guest for about 200 times, but no kernel panic occured again. (In reply to comment #6) > Hi, > I tried to boot RHEL4.9 guest for about 200 times, but no kernel panic occured > again. Why RHEL4.9? The bug title talks about rhel5.6.

The bug title talks about rhel5.6. Sorry, type error, my fault. I mean it's RHEL5.6. Closing the bug since it is not reproducible. Reopen if you see it again. |
