I've applied the patch, but the oops is a kernel panic, so I can't generate a dmesg including it. ;-) Here's the dmesg output from a fresh boot (runlevel 2): http://www.sisk.pl/kernel/debug/2.6.22-rc4-mm2/dmesg.log Here's a picture of the oops taken after a failed attempt to suspend: http://www.sisk.pl/kernel/debug/2.6.22-rc4-mm2/during_suspend.jpg Here's a picture of the oops taken after a failed attempt to offline CPU1 using 'echo 1 > /sys/devices/system/cpu/cpu1/online': http://www.sisk.pl/kernel/debug/2.6.22-rc4-mm2/after_offlining_cpu1.jpg [Sorry for the quality of pictures, I couldn't get anything better.] Greetings, Rafael -- "Premature optimization is the root of all evil." - Donald Knuth - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
