Hi all, I'm running 2.6.31 on a dual PIII Xeon 550Mhz box running Debian unstable, very much upto date. I've got two IDE disks, two SATA disks, two SCSI boot disks, two DLT7k tape drives and a tape library. All on seperate controllers. I'm trying to erase a DLT7000 tape, but I can't interrupt the 'mt -f /dev/dlt7k-right erase' command. I see in dmesg the following: [1464778.472497] INFO: task mt:14828 blocked for more than 120 seconds. [1464778.472599] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Or see if it's actually making any progress? The library doesn't happen to have a window, so it's hard to see the drive lights without opening it up.
