Hi all,
I hope this doesn't cover too well trod ground but I couldn't find any
good answer to it in the archives. I recently decided to switch to Mandrake
from Red hat when 7.1 came out. One of the statements I saw sent around about it
was that it natively supported the HPT366 UDMA66 interface that is part of the
BP6 motherboard. Mandrake does successfully work and install on a drive that
is on that bus but the performance I'm getting is horrible, worse than the
drives I have on the BX chip set's native IDE interface.
I have tried doing "hdparm -d1 -X66 /dev/hde" but the system just locks up
after a few seconds. I've also tried various variations on that but none seem
to work and most lock the machine up.
Here is a sample of the output from hdparm:
[root@gratz1 /root]# hdparm -i /dev/hde
/dev/hde:

[root@gratz1 /root]# hdparm -t /dev/hde
/dev/hde:
Timing buffered disk reads: 64 MB in 23.67 seconds = 2.70 MB/sec
as you can see I'm only getting 2.7 MB/sec when I should be able to get around
20MB/sec
Here is info from dmesg regarding HPT366:

If anyone can help me with this one I will send you a six pack of your favorite
