Hi Andre,

Hi,

I need some help with Linux kernel 2.2.19. I added Andre Hidrick's IDE-patch
to get Ultra-DMA for my IDE disk. That kernel has worked for a month.
Yesterday I decided to activate SMP to really use both of the CPUs in the
system. That didn't work. The system hangs during boot phase, no oops or
other error messages, just a silent stop.

First of all I have a question, should SMP work with Hidrick's IDE-patch?
If so, what could be wrong?

For the moment I don't have to much information to give to you, but I can
get what ever you want when I get back home from work.

I compiled the none-SMP kernel at 22nd of April, which means that the
IDE-patch must be older than that. I run a Debian 2.2 (Potato) system.
The motherboard is a Micro Star 694D-Pro with two PIII-850 CPUs,
256 MB RAM, etc.

The only information I have for the moment is a "dmesg" output from my
non-SMP functional kernel and two .config from /usr/src/linux/ one from the
functional none-SMP and the other for the problematic SMP-version.

Of cause the dmesg outputs differ depending on the kernel type but I have
inserted a pointer that show where the SMP-kernel friezes. As the kernel
friezes I have to write don't the output by hand and I din't have the time
to do it yesterday evening.
