The cause for this has been found; it's an "experimental" (read "buggy") chipset feature that some bioses enable; newer kernels will disable this feature again :( I have the same problem on Abit KT7A-RAID v1.3, but NOT on same board with revision 1.0. The problem is worked around by using "noathlon" kernel commandline. Using the newest kernel (2.4.16) does NOT solve the problem. Eirik Thorsnes I'm sorry, the motherboard revision in my last comment should be 1.2 not 1.3. I'm using the latest bios (rev. 64). Eirik Thorsnes Closing: this is the old via chpset flaw that current kernels work around |
Description of Problem: On a system with AMD Athlon processor and Abit KT7A v1.3 mainboard, Red Hat Linux 7.2 will crash during the init phase, but only if athlon kernel is used, the i686 one works just fine. I am unable to reproduce this problem on older revisions of the KT7A. Version-Release number of selected component (if applicable): 2.4.7-10 or 2.4.9-13; %{ARCH} = "athlon" How Reproducible: Every time Steps to Reproduce: 1. Install Red Hat Linux 7.2 2. Boot the system Actual Results: The kernel appears to load correctly, but a crash dump occurs after a few init steps; it does not happen at the same point every time. The useful sections of the trace disappear off screen before I'm able to read them properly, but I suspect that the problem is related to memory accesses. Expected Results: The system boot. Workaround: Boot in rescue mode, install i686 kernel - or - Replace the mainboard with an older revision, e.g. v1.1, of the same model Additional Information: I have tried different versions of the mainboard BIOS, and always get this problem. On the older (v1.1) board it is the other way around; I never get this kind of failure no matter what BIOS revision I use. I suspect that this is really a mainboard issue, but I'm reporting it here for two reasons: 1. Just to let you (i.e. Red Hat) and everyone else know that there may be a problem with this particular mainboard, and that a workaround exists. 2. Maybe you should upgrade the installer to address this kind of problem, e.g. by allowing the user to select processor type.
