From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.0.2 (X11; Linux i686; U;) Gecko/20011228 Description of problem: When i installed the RedHat Linux 7.2, using both kernels 2.4.7-2 and 2.4.9-13 the sistem freezes on boot. The motherboard is new and was changed recently, and is an ASUS CUV4X-D, with an Apollo Pro133A Chipset. I used the smp version of the kernels mentioned above and compiled a custom one and the result is the same. The curious is if i boot the old linux instaled on the machine, a Conectiva 5 Linux based on a 2.2 linux kernel, all things works fine!!! Version-Release number of selected component (if applicable): kernel smp 2.4.9-13 and custom ones. How reproducible: Always Steps to Reproduce: 1.Simply boot the sistem using the smp version of the kernels provided by RedHat. Actual Results: I have compiled the kernel 2.4.9-13, withou sucess. I am going now to try a BIOS update. Expected Results: i am here reporting this, waiting for help !!!! :-)) Additional info: The computer is an ASUS CUV4X-D, with 2 PIII 1GHz and 1Gb of ram and is a part of a Cluster Beowulf. We are upgrading this Beowulf, changing the motherboards and the Linux version. Actually, we are using a Conectiva Linux 5, based on Linux Kernel 2.2, and in this linux, with his kernel version, the sistem works fine and no errors are reported. I got this message with both kernels: WARNING: unexpected IO-APIC, please mail to linux-smp.edu I think this is a chipset issue.
Ok I think you're looking for the folling: In the bios settings there's a setting called 'MPS 1.4' or similar (depends a bit on the exact bios version you have). If you change the value of that it will work (well it did for others, I don't have this mobo myself)
I am making tests now, and when i disabled this setting and all wokrs fine. I have made this after read the comments about this issue. Anyone knows what 'MPS 1.4' means? Thanks a lot.
MPS stands for "multiprocessor specification" and comes in spec level 1.1 and level 1.4. Somehow there's a "miscommunication" between the linux MPS code and some ASUS bioses for format 1.4 tables. Who's to blame is unsure yet (but it's only on ASUS motherboards :). 1.1 tables are a slightly different format and seem to work well.......
