The kernel actually does check what it can |
Created attachment 21806 [details] dmesg Note: I’m running an Ubuntu kernel. The tree selector did not have an “Ubuntu” or “Other” option. Since the installation of DeviceKit-disks, the system startup blocks for almost a minute on two of my computers when udev runs /lib/udev/devkit-disks-part-id for fd0. Neither of the computers in question have a floppy drive, but Linux says: [ 2.467794] Floppy drive(s): fd0 is 1.44M I probably could workaround the problem by disabling floppy drives in BIOS settings, but one would think the OS could realize a drive doesn’t exist automatically. % tail -n0 -F /var/log/syslog & time sudo /lib/udev/devkit-disks-part-id /dev/fd0 DKD_MEDIA_AVAILABLE=1 Entering MS-DOS parser (offset=0, size=4096) Jun 8 13:39:53 virhe kernel: [131622.526230] end_request: I/O error, dev fd0, sector 0 Jun 8 13:40:06 virhe kernel: [131635.590496] end_request: I/O error, dev fd0, sector 0 Jun 8 13:40:06 virhe kernel: [131635.590517] Buffer I/O error on device fd0, logical block 0 read failed (Input/output error) Exiting MS-DOS parser Entering Apple parser Jun 8 13:40:19 virhe kernel: [131648.654322] end_request: I/O error, dev fd0, sector 0 Jun 8 13:40:19 virhe kernel: [131648.654343] Buffer I/O error on device fd0, logical block 0 read failed (Input/output error) Leaving Apple parser No known partition table found No partition table found on /dev/fd0: Input/output error sudo /lib/udev/devkit-disks-part-id /dev/fd0 0.01s user 0.02s system 0% cpu 52.301 total Interestingly, lshw does not list a floppy drive at all.
