Yes, I was just trying to show how stable the old one was ;) I tried
it clean with no idebus and no hdparm tweaking, and get the same
results. The only thing that prevents the crashes is disabling DMA
(hdparm -d0), but DMA works fine with the other kernels _and_ is
detected and accepted by the kernel during boot as usual.
A quick peek at /usr/src/kernel-2.4.x/drivers/ide/piix.c tells me
that there are no settings for my specific chipset, but even
compiling with only the default kernel DMA support (no PIIX) gives
the same problems. My guess is that it is a timing related problem,
but I have no idea as of how to change the timings so I can try
them on my system.
Again, the same kernel configuration works fine up to 2.3.99-pre6.
I'm currently chugging along with 2.4.0-test1-ac8 with no DMA (about
5Mb/s transfer rate).
