5.3 standard or custom kernel, several different machines.
>Description:
"ata" driver detects too high an xDMAx speed, several hw
combinations, 5.3-RELEASE. Incorrect cable identification?
1/ PCchips (SiS) P///-800 mobo, Pioneer DVD117, *40* wire cable, the
dvd is configured for UDMA66 (partially works, unreliable).
2/ Various socket 7 mobo, PCI card with CMD0649 chip, Maxtor D740X-6L
HDD (probably others also), *40* wire cable, hdd is configured for
UDMA100 (doesn't work).
(I have probably seen this on other hw combinations also.)
"atacontrol" can be used to reconfigure a dvd after booting. The worse
problem is hdd, trying to boot install media and do an install.
>How-To-Repeat:
Same hw?
