Thank you for reporting the problem. I'll look into this along with the reported mount problem on pen-drives. If you can hit the keyboard in another terminal during the interval, please try the following dump feature: # echo 1 > /proc/sys/kernel/sysrq # echo d > /proc/sysrq-trigger # dmesg > dmesg.out.1 (this shows all locks that are held) # echo t > /proc/sysrq-trigger # dmesg > dmesg.out.2 (this will dump a list of current tasks and their stack) Note that, your kernel has to be built with the kernel option: CONFIG_MAGIC_SYSRQ=y to enable this feature.
