I have run into similar problems. I was able to get the Slakware 2.3.0 kernel
installed, but the setup program originally crashed when installing the C
compiler. I had some luck moving the scsi id's of my devices around, now it
just crashes about halfway through the installation of X.. The error message
that I received was very much the same. I was able to run this same
configuration with an earlier version of Slakware (2.1.0 or there abouts)
without incident. The only variables thrown in are the Hercules Dynamite
(ET4000) video and a new 2.1 GB SCSI Hard drive from Conner. After the crash,
I am still able to get to the hard drive, but am unable to get to the triple
speed NEC CDROM (which, of course has the Slakware CD). Phoooeyy.

I'll keep beating on it. Please let me know if you have any luck.

Did you try to set "Enable Disconnection" to NO.
(It's in the boot-up menu of the adaptic)

I've got an AMD 486Dx4/100. My motherboard (I have no idea what brand...)
can run the VLB backplane at either 50MHz or 33MHz. I've also got an
Adaptec AHA-2842VLB card. What I found was that if I run the backplane at
33Mhz everything works fine. If I run the backplane at 50MHz then the
Adaptec card gets really confused.

If you can, I'd suggest backing off you VLB bus to 33MHz and see if that
helps.

Cheers,
Bruce.

the above story is the same for me I have a nexgen 586 p-90 with a adaptec 2842 scsi
card and I am getting the same error. Anyone out there fix this problem yet? or am
I out of luck running linux?

both a cdrom and a hard drive. the bios is loading at bootup

how do you disable it?

Great idea, considering the VLB specification is so badly abused:
0 slots at 50 Mhz (motherboard video only)
1 slot at 40 Mhz (most VLB boards are not guaranteed to work)
2 slots at 33 Mhz
3 slots at 25 Mhz

VLB is a true local bus, with no buffering on the signals. The design of
the motherboard greatly affects the bus, so it is possible to use more
slots on a good motherboard (or fewer on a piece of junk).

Some motherboards also support VLB wait-states to help.

The PCI bus is a "mezanine", or buffered local bus, and is not limited in
the number of slots by bus speed.

I just installed my Nx586-90, and I have had really no problems with it
execept for the lack of a math coproccessor. I have a Caching VLB
controller, that opperates much like a SCSI controller, with its own bios
and all. It reports that my VLB is running at 50mhz, which luckily my
card is supposed to be able to run at, but I know that many VLB cards
have trouble handeling speed over 33mhz. There is a jumper on the
motherboard (JP 4-2) that controlls the VLB speed, there is also
a setting under the bios Advanced NxVL setup that effects the
vlb wait states. You might try messing with these to try and slow
it down.

To disable the message recompile a kernel without pci support:)
