SubjectRe: Linux 2.1.125ac1
Hello Alan,

I've checked your ac1 patch and my machine hangs hard right after the
first line coming up on screen.

Linux version 2.1.125 ... --> hang

Machine is ('clean' 2.1.125):

You can see that I use the IDE stuff only as modules. During the first
hard disk or CD-ROM access every thing except DMA isn't enabled as
default for CD-ROM is OK. But then I can't get DMA mode any longer until
the next boot. Do you thing there is a solution for this?

The famous VIA MVP3 chip set isn't correctly recognized for now:

Please can you tell me how I can enable 'Write Allocation" for the K6-2
in the kernel? --- Do I need a patch?

BTW I use the 'tcsh' here and do not get any coredumps :-(
Yes, I have set 'coredumpsize' to 'unlimited' and compiled with '-g' and
linked with '-lc_g' to be on the sunny side. Should I have something
enabled in the kernel? I've tested 'bash' but it changed nothing :-(

Regards and hope we will see 2.2 soon.
