Hey, The closer I look at the 8.2 install I did on this new Abit nForce board the more glitches I discover.
In the course of tracking down why the kupdated daemon would periodically guzzle CPU time whenever I did a lot of disk I/O I discovered (via hdparm) that my two Maxtor 80 drives (which I'm hoping to use for a partial soft raid setup later on) were about as poorly configured as possible. Running hdparm with the -Tt benchmark flag showed a pathetic 3.2 mb/sec for buffered disk reads (buffered cache reads were 297.57). I tried tweaking them for the ATA100 channel they're installed on thusly: hdparm -c1 -d1 -X69 /dev/hda but got a rather unexpected message back: setting 32-bit I/O support flag to 1 setting using_dma to 1 (on) setting xfermode to 69 (UltraDMA mode 5) ide0: Speed warning UDMA 3/4/5 is not functional I/O support = 1 (32-bit) using_dma = 1 (on) I did another benchmark run and got 22.15mb/sec. Checking hdparm -i /dev/hda it claims the disk is actually running in UDMA 2 mode. A friend with a Western Digital drive (ATA100, 7200rpm, 40gb) gets around 40mb/sec in UDMA 5 mode for buffered disk reads. He's running RedHat 7.2 which I believe has a similiar kernel version. Seems like there's a lot of possible problems (bad install, bad hardware, wrong drivers, disks that are too new to be well supported, motherboard that's too new to be supported...) Anyone have a similiar experience or a good idea of where to start? cheers, ::mark
