Date: Fri, 7 Dec 2007 17:53:47 -0500 From: "Parag Warudkar" <parag.warudkar@...il.com> To: LKML <linux-kernel@...r.kernel.org> Cc: "Andrew Morton" <akpm@...ux-foundation.org>, venkatesh.pallipadi@...el.com, "Linus Torvalds" <torvalds@...ux-foundation.org> Subject: BUG: soft lockup - CPU#1 stuck for 15s! [swapper:0] Got this on today's git (2.6.24-rc4) while compiling stuff - Looks like it is related to CpuIdle stuff. I chose CONFIG_CPU_IDLE for the first time so I don't know when this was introduced. This is on x86_32, SMP. BUG: soft lockup - CPU#1 stuck for 15s!
