Created attachment 311326 [details] kernel panic log Same problem experienced 4 days after installing 2.6.9-67.0.20.ELsmp kernel on a system that previously had no stability issues.
Comment 4 Phil Hale 2008-07-09 01:04:14 EDT
seeing a similar issue on two of my 4.6 boxes running MailScanner as MX filters.
Comment 5 glshank 2008-07-10 10:22:39 EDT
Same here. It panics during heavy IO via MySQL.
Comment 6 Ivan Vecera 2008-07-10 11:34:13 EDT
The problem is in next_thread function, I'm assigning this issue to Vitaly.
Comment 7 Vitaly Mayatskikh 2008-07-10 12:14:15 EDT
This is a race between release_task() and sys_times()->next_thread()
Comment 14 Vitaly Mayatskikh 2008-07-11 19:03:31 EDT
Created attachment 311625 [details] lock sighand->siglock in release_task() This patch fixes the problem
Comment 16 Vitaly Mayatskikh 2008-07-14 04:25:07 EDT
Created attachment 311684 [details] simpler version of patch Unhash process with locked sighahd->siglock.
Comment 17 Tom Sightler 2008-07-14 09:42:11 EDT
We had two of these this weekend. Previously stable systems were upgraded to the latest kernel and two locked last night, not even making 24 hours. In my opinion this bug should be urgent.

We've just had an RHEL 4.7 box crash with this one. Is there any timescale for the fix to be released through the normal channels?
