Message-ID: <20110805010038.GA18148@redhat.com> Date: Thu, 4 Aug 2011 21:00:38 -0400 From: Dave Jones <davej@...hat.com> To: Linux Kernel <linux-kernel@...r.kernel.org> Cc: Linus Torvalds <torvalds@...ux-foundation.org>, Andrew Morton <akpm@...ux-foundation.org> Subject: list corruption in the last few days. (block ? crypto ?) Sometime in the last week, something was merged which causes my laptop to lock up occasionally. I can trigger it most of the time just by doing a kernel build. When it gets to the final linking stage, it locks up hard. I finally managed to coax something out of usb console to get the traces below, which seem to implicate something in the block layer ? my root device is an lvm volume on an dmcrypt'd block dev, which might be relevant, as I don't see this happening on other machines with simpler setups. I'm going to try bisecting, but it might take me a few days, because it's such a pain in the ass to reproduce this reliably.
