2.4.1 DAC960 driver bug or what's going on?

2.4.1 DAC960 driver bug or what's going on?

[Silviu Marin-Caea]

Hardware:
A plain and honest Intel BX mainboard (AOpen AX6BC with latest BIOS
update), Pentium II/333, 64MB RAM, dumb PCI 1MB video card, Mylex
AcceleRAID 170 PCI controller, Quantum Atlas IV hard-disks.

Kernel 2.4.1

I want to install the system on the RAID volume, and for this purpose I
compiled the DAC960/DAC1100 driver into the kernel.

Made a boot floppy from RedHat distribution images and copied my kernel
with Mylex support on it.

Here are the relevant messages

[...]

DAC960: Copyright 1998-2000 by Leonard N. Zubkoff <lnz@dandelion.com>
Kernel panic: DAC960: Logical Drive Block Size 0 not supported

I really don't know what the other device on IRQ 11 would be, since
there are no other add-in cards than video and RAID controller.

Same thing happened on an EPoX mainboard, before I tried the controller
with this hardware.  No matter what IRQ Mylex gets, linux says there's
another device using it.  What would be that device?  PS/2 mouse
controller, perhaps?  Why does it stick to Mylex?

Thank you for your help.

That bit is fine

That IMHO isnt the problem

Works with kgcc.  Thank you Alan.

I thought RedHat fixed their compiler.

Im not yet sure if its the compiler or the DAC960 driver which is at fault
here. I'm looking at some 'interesting' reports about bitfield behaviour
which is why I suspected this
