2.6.x Athalon XP 2700+ A7V600-X mb slow


I just upgraded my hardware yesterday after a downgrade. I was running 2.6.8.1 (Slackware Current) on a AMD-Duron 700mhz system with no problems at all. The hardware went south, and thinking it was the software I did a reinstall of Slackware 10 using 2.4.26 and then 2.4.27. I moved over to a PII 400mhz using the stock kernel until I upgraded the hardware.

I upgraded the mb, processor, and memory. I kept all other components the same. I moved to the 2.6.9 kernel and started noticing some issues:

1) When I extract large archives (i.e.; kernels) there is a tendency for everything to slow down. The mouse gets jittery, typing is paused, etc.

2) If I burn a CD in ATAPI the same thing slowness occurs until the burn process is complete.

None of this exists in 2.4.27. Everything runs smooth.

I have tried 2.6.9-ck, 2.6.10-rc3, and 2.6.8.1 all to the same effect. I have tried turning off the premptive kernel features, and that did not make a difference.

The only other change I made was to move from the sb live I had in there to the AD1888. I used the sb live with the 2.6.9 kernel so moving sound cards is not an issue.

I am wondering if this is has anything to do with the ide controllers and such. I am still using my old 20gb hard drives which may be dma/66 or ealier. The controllers I have now support up to 133 so perhaps I am missing something in the config. The problem only seems to happen with regards to ide activity so far.

System specs:

Asus A7V600-X mb VIA KT600 North Bridge and VIA VT8237 South Bridge
Athlon XP 2700+
512 mb DDR ram
Nvidia GForce FX 5200 w/128mb
VT6102 Rhine-II ethernet controller
AD1888 audio
Haupuage BT787 WinTV
Firewire Card: Via Tech.

2x Maxto 20gb drives
Compaq DVD drive
Asus CDRW

All ide devices have dma on (right now and I belive they do in the 2.6.x but I would have to double check again)

PS/2 keyboard
USB logitech optical mouse
USB Epson Perfection 610 scanner

Well, posting here, and collecting my thoughts, seemed to help produce the answer. It was the dma issue. None of my drivers had dma enabled. I compiled in the VIA 82Cxxx driver and now DMA is being enabled at boot. Everything is running smoothly again on 2.6.8.1. Guess it is time for 2.6.9-ck or 2.6.10-rc3...
