It's a 2x Athlon XP 1800+ on a Tyan mobo, AMD 760MP chipset, with an Adaptec SCSI controller and 512Mb DDR SDRAM. I'm not a Linux newbie at all, but I've never tried running it on such exotic hardware before, and it doesn't seem happy.... I installed Red Hat 7.2 and the machine boots fine, using SMP or UP kernels (Red Hat 2.4.9-7), but totally HANGS at the login prompt. Can't type, can't reboot, can't do anything. Single user mode _does_ let me in, however, and this is the only progress so far. I then tried building a custom 2.4.15-pre4 (on another machine), which compiled perfectly happily, and I installed this on the server. It panic'd due to failure to mount the root filesystem. I made an initrd.img, and it then got further (detecting and initialising the SCSI controller), but still panic'd with the same message. I then threw down the gauntlet and installed the rawhide Athlon SMP kernel (based on 2.4.13) which also booted fine but HUNG at the login prompt, as above. Finally, I tried the i686 version, which spewed out tons of error messages regarding "invalid symbols" in the ext3 module. Either way, I'm stumped. Am I up against an Athlon / chipset problem here, or is something else wrong? What do I need to do to get my custom-built 2.4.15-pre4 rolling - why can't it mount the root partition?
