SubjectIDE DMA hard lock at boot time (KT266A chpiset)
Date
Hi all, 

I'm using an elitegroup mobo (K7VTA3 / KT266A chipset; Athlon XP)
and I'm experiencing a hard lock at boot time when configuring the
kernel using `via82cxx support'. (No ctrl-alt-del, no sysrq, only hw reset)

[Without that I can boot without problems but I don't have DMA and thus
disk throughput is at less than 3 Mb/sec.]

The hard lock seems to happen during the first hd access and the hd light
stays on when the system is crashing.

Is that
- a known issue (hopefully not),
- a Linux kernel problem or
- do I have to blame the board (this is not completely unlikely as
I also have problems with two network cards which work without
problems in other boards and same kernel)

Is the KT266A chipset's DMA supported at all? (The vt82cxx driver
source code lists several chipsets including KT266 but not KT266A.)
