Just to confirm: The dell-wmi messages do not show up when the monitor is plugged in, but only when xrandr is run and the monitor goes black?
If you let it stand for a couple of minutes before hitting Sysrq-REISUB, does the BUG: Soft lockup line show up eventually, without you rebooting? Otherwise, my knowledge is exhausted on this one, and I hope someone with more kernel knowledge can bring this to the attention of the right upstream. -- [arrandale] VGA port not working on Dell Latitude E6510 https://bugs.launchpad.net/bugs/607783 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
