Just the hddtemp process is in D state (blk_execute_rq) and unkillable, other processes run fine. The startup script calls hddtemp -wn /dev/sda. /dev/sda is a CF slot in a USB 6-in-1 memory card reader, currently empty. /proc/partitions shows only 2 ide disks. Since hddtemp is not converted to SG_IO yet, the kernel logs program hddtemp is using a deprecated SCSI ioctl, please convert it to SG_IO but this should not cause hddtemp to hang. This is another case of process hanging in blk_execute_rq, see the recent thread "readcd hangs in blk_execute_rq" (also reported by me but about a different computer). I have noticed it some weeks ago but didn't have time then to investigate and disabled hddtemp. Today I looked at it again and now I'm reporting it. -- Meelis Roos (mroos@linux.ee) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
