Thanks. Have you tried turning lockdep off, if that still triggers? Aparently the first BUG leaves the spin lock locked, and all subsequent accessess to it lock the machine hard. We'll need to see what goes wrong inside lockdep. Could you please run addr2line -e vmlinux c0133034 (passing the path to the vmlinux binary of the crashing kernel to the -e parameter). -- Jiri Kosina SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
