ACPI + Floppy detection problem in 2.6.8.1-mm4
Since patching from 2.6.8.1 to -mm4 I noticed that I can no longer modprobe the floppy driver. It is failing to detect the floppy drive and controller it seems. Looking at the output from dmesg I have this:
[-snip-]
inserting floppy driver for 2.6.8.1-mm4acpi_floppy_resource: 6 ioports at 0x3f0acpi_floppy_resource: 1 ioports at 0x3f7
floppy: controller ACPI FDC0 at I/O 0x3f0-0x3f5, 0x3f7-0x3f7 irq 6 dma channel 2 Floppy drive(s): fd0 is 1.44M
floppy0: no floppy controllers found
[-snip-]
I saw in the -mm4 changelog that ACPI-based floppy detection was added, which seems to be working, but the floppy driver doesn't seem to think the controller/drive exists once the ACPI enumeration is done. I just noticed the no_acpi floppy module param in the source, so I will give that a try. Since the ACPI code seems to be picking up the controller and drive just fine, I doubt this is limited to just my system (i.e. my ACPI tables are screwy etc.).

I just tried the no_acpi module param and the floppy driver loads and works just fine, so this is indeed an ACPI related.
