Subject: hddtemp hangs with USB SCSI disks; blk_execute_rq again
Date: Tue, 26 Oct 2004 08:36:00 +0300 (EEST) [thread overview]
Message-ID: <Pine.GSO.4.44.0410260827240.8730-100000@math.ut.ee> (raw)
Hi,
hddtemp startup script hangs on my machine. 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.
