Yesterday I installed Abit Hot Rod66 udma controller with a Maxtor 96147U8
to my aging linux system. I patched my 2.2.16-kernel (which allready had
reiserfs patch in it) with Hedricks ide-patch and all seemed to work fine.
Unfortunately a problem manifested itself when copying file through
samba-share over 100M ether (with digital 21140 card using tulip driver):
machine just stopped with following on console "timeout waiting DMA
ide_dmaproc: chipset supperted ide_dma_timeout func only: 14" (or 12, I
got both at different times).
I then tested different kernel versions, 2.4-test3 and 2.3.99-pre9. Same
result.
I tried my IBM DJNA-352030 to the machine and found out that with the IBM
hd there was no problem.
Only solution I was able to find was to add the maxtor drive to
/usr/src/linux/drivers/block/hpt366.c bad_ata66_4 and bad_ata66_3-lists so
it would be forced to udma/33. It sees to work fine.
I read that people have had problems running maxtor drives with Hot Rod66
but saw no mention of 96147U8, neither is it in the forementioned
bad_ata66-lists.
Just my 2 cents.
