kernel oops in resched_task
Hi, I got this oops while running open-iscsi on a CentOS 5.3 machine (don't know how to recreate it). it crashes while trying to wake up the work queue after queuecommand was called. Has anyone seen something similar?

I'd suggest you to upgrade to 5.4 and see if it still happens. -- Pasi -- You received this message because you are subscribed to the Google Groups open-iscsi group.

Are you using the kernel modules that come with 5.3 or the open-iscsi ported ones? -- You received this message because you are subscribed to the Google Groups open-iscsi group.
