Hm, I always use a (hardware) serial console, but I think on default loglevel the sysrq-output goes to dmesg only, so you have to adjust the loglevel also. Normally I have a ssh into the box running with a tail -f /var/log/messages. This locks up very seldom. Have you tried some sysrq combinations? It might work, even when the keyboard looks locked up in all other respects. > > Serial console with USB serial adapter? > > Thanks, -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
