From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: When I use "reboot" to restart my RedHat 7.1 (on Compaq Presario 1266, NeoMagic 128 XD (MM2160)), the system restarts, and starts loading kernel, then I see some funky color characters on screen, then the boot seems stopped, system is hang and I have to use "Power Off" button to restart system. However, if the system is bootup from power on I never see this problem. It seems to me that "reboot" does not cleanup something (which I don't know). How reproducible: Always Steps to Reproduce: 1. boot up Linux system (RedHat 7.1) 2. Logon as "root" and type "reboot" 3. After system reboot and LILO, system hangs after "Loading kernel..." with random garbage color characters on screen. Actual Results: It happened again. Additional info:
Note: "reboot" worked perfectly when I used RedHat 6.x and 7.0
More info: "reboot" sometimes causes "LILO" string does not display completely. This is kind of random, so far I saw these cases: " ILO" " LO" "L LO" (the first 'L' is in green). But they all hang when system tries to load kernel. If I use "vga=788", then the system loads the kernel, but fails/hangs later, one time was when it detects USB devices, the other one is when it's about to mount harddisk. If I choose "Windoze 98" (dual-boot) from the problematic LILO, the system seems recovered for Windoze 98SE.
This bug report sounds like it has absolutely nothing to do with the usermode package whatsoever. It sounds more like a kernel problem, or more likely really broken hardware or misconfigured BIOS or bad RAM or something. Arjan, your thoughts?
Hmmm, looks weird but I agree with Mike that it's not a fault of reboot. It's very hard for me to reproduce the problem and it seems to me that this issue is pretty hardware specific. If something like this happens again to you with a recent release and can be reproduced, please report it again. Thanks, Jindrich
