I have a new laptop, from R-cubed Technologies. They are using an ASUS
motherboard in it. I too am seeing these 30-second hangs, but only when
I'm actively running Windows-XP Pro in a VM-Ware session (at least
that's when I notice it). They are causing SSH and my Windows VPN to
drop the connections due to timeouts.
I've watched the speed of my disk drive drop from UDMA/133 all the way
down to PIO0 (and it continues to try and drop from there, tho there is
no place to go from there....)

I have just recently set:
hdparm -S 0 /dev/sda
Hopefully, this will keep the drive from spinning down. Do I need to
put this in rc.local? RH recently removed the hdparm stuff from
/etc/sysconfig....
hdparm (thanks for the pointer) shows that idle shutdown was
configured
for the drive. A little digging turned a two-hour idle timeout.
Curiously, the problem started after about two hours, but definetly not
idle for that time. I disabled idle timeout, and after two hours I get
the following. Repeats every 15 minutes or so.
This definitely does NOT sound promising.

I'm going to talk with th R-cubed folks RSN about this (and a couple of
other problems). If we come to a solution, I'll post it here....
