| On CentOS/RedHat, the log entry is blk_update_request: I/O error, dev fd0, sector 0 Those error messages can be triggered by facter filesystems or facter mountpoints or an operating system command such as fdisk -l that enumerates all available block devices when the floppy driver is loaded but there is no floppy device. Testing show that if I disable the floppy module with rmmod floppy the error messages stop. Remarkably, if I re-enable the floppy module with modprobe floppy, the errors messages do not reoccur until after the next reboot. Search the internet for blacklist floppy for solutions at the operating system level. |
