system hang
my system has begun to hang momentarily, every .5 minutes or so, e.g., when
typing the echo will lag. Another new thing I see in the system is the
following message at boot time:
Executing: blockdev --setra 256 /dev/hda1
proc not found in PARTITIONS.
/proc not found in PARTITIONS.

ETC
i also see hdparm being executed in the same messages, although I can't find
anything that looks like it is causing the disk to spin down at frequent
intervals. also, i ran 'atsar', and it shows what seems to be normal disk
activity, e.g., writing to and closing a file in a perl script is reflected
in the atsar output as an immediate disk hit.
Just prior to the appearance of this problem I installed the suspend2-related
software; suspend2 support was in the kernel out of the box, but I had to
install other stuff to get the system to acutally suspend. as far as i can
tell nothing related to suspend2 happens unless i run a script to do the
suspend. Kernel is (2.6.16.4). The machine is a toshiba satellite 1135.
Any feedback would be appreciated.
