I've got here a brand new IBM xServer 236 and try to install debian sarge with kernel 2.6 and I'm now at the end of my knowledge. *sigh*. When I had a test machine, all went fine, both SMT Processors were detected and the system was stable with 4 Processors. Now, that I have the production machine (newer BIOS), the thing drives me crazy...

Problems: No SMT, PCI devices complaining in dmesg about invalid IRQ, probably buggy MP table, sometimes losing timer ticks on boot and kernel panic. I also tried to correct the DSDT (sorry, I didn't know better), but the iasl did not find any errors, so what... The intresting fact is, that the Redhat Enterprise Linux 3 Kernel (2.4.21 with 380 patches/1,6x10^6 lines of patch) has no problems with the RSDP. I could not identify the patch, which made the RSDP work.... Please help me! Make my 236 work with a minimum of patches... -- Klaus Muth HAGOS eG Industriestr. 62 fon: (+49) 711 78805-86 EDV-Programmierung 70565 Stuttgart fax: (+49) 711 78805-35 http://www.hagos.de Germany mailto:muth-5lHx5lHeYlQ@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
