Earlier 2.4 kernels boot fine if I supply mem=120M manually (installed memory minus shared memory). 2.2 kernels boot fine with no command-line arguments. Shuttle FX41 mobo; Via KM266 chipset; onboard video. This seems to be similar to Justin Heesemann's problem: http://www.uwsg.iu.edu/hypermail/linux/kernel/0208.2/0772.html I assigned shared video to 0M in the BIOS but the system hung at the same place, would only boot 2.4.19-pre6 with mem=120M (I presume; no video to be sure that it was the same place). This suggests that maybe it's not shared video memory that's the problem, and mem=120M in some other way worked around the issue on earler 2.4 kernels. Some 2.4.19-pre7 change to arch/i386/kernel/setup.c definitely seems to have rendered these systems unbootable. dmesg 2.4.19-pre6 / 8MB shared video RAM ---- Linux version 2.4.19-pre6-morigu (root@morigu.merlin.org) (gcc version 2.95.4 20011002 (Debian prerelease)) #2 Sat Dec 14 00:21:12 EST 2002 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000a0000 - 00000000077f0000 (reserved) BIOS-e820: 00000000077f0000 - 00000000077f3000 (ACPI NVS) BIOS-e820: 00000000077f3000 - 0000000007800000 (ACPI data) On node 0 totalpages: 30720 zone(0): 4096 pages. zone(1): 26624 pages. zone(2): 0 pages.
