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-mm4 acpi_floppy_resource: 6 ioports at 0x3f0 acpi_floppy_resource: 1 ioports at 0x3f7 floppy: controller ACPI FDC0 at I/O 0x3f0-0x3f5, 0x3f7-0x3f7 irq 6 dma chan= nel 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.). --=20 Aric Cyr (http://acyr.net) gpg fingerprint: 943A 1549 47AC D766 B7F8 D551 6703 7142 C282 D542 --wac7ysb48OaltWcw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFBK+4MZwNxQsKC1UIRAhAXAKDBCPKydCVufP59gjJbmgOpiAhCCACgjVYd 4wM3H+5DGkYLapDV1PcYCZI= =WZ98 -----END PGP SIGNATURE----- --wac7ysb48OaltWcw--
