FYI, I've been chasing an occasional hang with lapdock and it might be related to the usb phy switching between usb and uart mode spontaneously. And then the usb traffic can cause a sysrq trigger potentially when the glitch happens. Not sure yet why it happens, it might be related to lost cpcap interrupts still. Anyways, so far looks like doing the following may have prevented it. Well at least for about four days of uptime now: # echo 0 > /proc/sys/kernel/sysrq And no red screens here yet either. Care to check if this might somehow also prevent your red screen issue?
