Ghost Floppy Disk and ACPI
I'm trying to upgrade my Slackware 10 (2.4.26) to the 2.6.7 kernel. Everything went well until reboot, when the system froze right after "Using anticipatory io scheduler", and a "no cont in shutdown!" message would show up. I went back to the 2.4 kernel and noticed that that's where the floppy modules are being looked for. I figured this could be an IRQ conflict and I booted again with the 2.6 kernel with "acpi=off", and the system booted fine (all the useful laptop stuff and sound gone, though). I've attached the successful boot sequence below, right to the point where the system would freeze without the acpi=off option.
The question is, is there any way to get the kernel not to look for the floppy controllers? I looked in /etc with the hope that I could comment something out, but no luck. Do I need to recompile the kernel with no floppy disk support or something?
I should add I have a toshiba 5005 laptop w/ an external USB floppy drive, so it's no surprise that "floppy0: no floppy controllers found" shows up at that point in the boot sequence.

Did you use a stock kernel or compile one on the laptop you are using?Long live the revolution!
Have a nice day.
If you want real change vote Libertarian!
