UDMA problem with Maxtor 7200rpm disk

[Jean-Francois Levesque]

Hi!

I have a problem regarding my new Asus A7V266 board with VIA KT266 chipset.  Byron Stanoszek told me to ask my problem to this list so here it is :

My hard drive is a Maxtor 5T030H3 ATA DISK drive (30 gig).  The problem is that I'm not able to read more than 7 MB/sec :

[root@xyz jfl]# /sbin/hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:  64 MB in  9.18 seconds =  6.97 MB/sec

[root@xyz jfl]# /sbin/hdparm -d1 -X66 /dev/hda

/dev/hda:
 setting using_dma to 1 (on)
 setting xfermode to 66 (UltraDMA mode2)
 using_dma    =  1 (on)
[root@xyz jfl]# /sbin/hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:  64 MB in  9.70 seconds =  6.60 MB/sec

[root@xyz jfl]# /sbin/hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 3736/255/63, sectors = 60030432, start = 0

I also have some idebus errors.

The problem seems to be the DMA (ATA100 compatible board and disk).

Here is a part of my dmesg output (on kernel 2.4.2) :

hda is my Maxtor 30 gig hard disk
hdd is a old IDE CDROM that was working very well but now I get a lot of errors.

IRQ problems?
DMA problems?

I use the 80-pin blue IDE cable.

I'm using kernel 2.4.2 (from RH 7.1) because when I try the 2.4.9 (from RH 7.1), I get "hda: drive not ready for command" error (when the kernel is checking for the partitions on the disk) and my system hangs (freeze) on this.  I also tried 2.4.12-ac5 (what Byron was using and it was working with his VIA chipset) and 2.4.16 (lastest stable version) but I have the exact same error (not ready for command).

Any idea?

Thank you in advance for your help!

PS: My disk also "freeze" my system for a few seconds (from 1/2 to maybe 3sec) while checking some data.
