From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-0.1.40 i686; Nav) When I /sbin/shutdown -r now (or equivalent), the laptop successfully shuts down and begins to restart, but halts before the boot loader (lilo) can start. The same situation existed in Red Hat 7.0, but the original kernel from Wolverine doesn't have this problem. However, i've since upgraded to a rawhide kernel (due to recommendations from those who'd know) and it no longer works. Reproducible: Always Steps to Reproduce: 1. Reboot 2. Watch Actual Results: It runs through the bios screen and halts before the "LILO boot:" would show. Here's what the screen looks like at halt: BIOS VERSION 12.03 Pentium II 333 MHz 0000640K System RAM Passed 0097280K Extended RAM Passed 0256K Cache SRAM Passed System BIOS shadowed Video BIOS shadowed Fixed Disk 0: TOSHIBA MK6412MAT CD-ROM Drive: Identified Mouse initialized <cursor> Expected Results: Well, I don't recall what the bios under the original wolverine kernel showed (I'm guessing it's the same as windows does), but when windows reboots (successfully), the bios output is much shorter, as if the bios has a separate routine it runs to reboot than standard. It looks like: BIOS VERSION 12.03 Fixed Disk 0: TOSHIBA MK6412MAT CD-ROM Drive: Identified Mouse initialized LILO boot: <cursor> Again, this failed reboot occurs under Guinness and Rawhide kernels, but the "stock" Wolverine kernel successfully rebooted. I never tried Fisher on the laptop, so I couldn't say how it worked. I hope this helps.
Can you try to use the following options as commandline options on the lilo-prompt? reboot=c reboot=h reboot=b reboot=w
Here's what I did to test this (in case it's invalid): LILO boot: [text as shown below] .... bash-2.04# shutdown -r now # if I got this far ... [wait for a lilo prompt] "linux single" it reboots, but the LILO prompt never occurs "linux reboot=c single" it reboots, but the LILO prompt never occurs "linux reboot=h single" it reboots, but the LILO prompt never occurs "linux reboot=b single" it reboots, but the LILO prompt never occurs "linux reboot=w single" it never loads in the first place: Loading linux............... Uncompressing linux... crc error -- System halted another thing to note, which I didn't see before (but perhaps you knew) when the LILO prompt never shows up, the "Press <F2> to enter setup..." prompt is still there at the bottom of the screen. Hope that helps!
Its crashing in the BIOS after the reset. That more than implies its a BIOS bug where the BIOS fails to correctly reset all the hardware after Linux ran.
Oh could you try "apm=realmode" as option ?
with linux single apm=realmode, linux single apm=realmode reboot=c, linux single apm=realmode reboot=b, linux single apm=realmode reboot=h, there is no change--it reboots, does the full bios check and freezes. With linux single apm=realmode reboot=w, it still didn't work, but it did use the shorter bios check seen when windows correctly/successfully reboots (Implying it's closer). Hope that helps
