I'm running FreeBSD 4.4-Release and had just copied kern.flp for 4.5-RC3 onto a floppy using dd. I mounted up the floppy without any unusual flags (and certainly not read only) as I wanted to put a boot.config file on there. I typed echo "/boot/loader -h" > /mnt/floppy/boot.config". The write failed, the floppy light stayed on and then suddenly the machine rebooted without warning. Alas I don't have a crash dump as my RAM is bigger than my swap space. I did notice several entries like the following (these were the last) in /var/log/messages after it rebooted: Jan 25 21:15:52 chunky /kernel: fd0c: hard error writing fsbn 16 of 16-18 (ST0 40 ST1 2 ST2 0 cyl 0 hd 0 sec 17) Jan 25 21:15:52 chunky /kernel: fd0c: hard error writing fsbn 56 of 56-63 (ST0 40 ST1 2 ST2 0 cyl 1 hd 1 sec 3) Jan 25 21:15:52 chunky /kernel: fd0c: hard error writing fsbn 64 (ST0 40 ST1 2 ST2 0 cyl 1 hd 1 sec 11) Jan 25 21:15:53 chunky /kernel: fd0c: hard error writing fsbn 16 of 16-18 (ST0 40 ST1 2 ST2 0 cyl 0 hd 0 sec 17) As mentioned, the floppy was not write protected, so I guess it was just faulty. However I was a bit surprised that the machine crashed like this. Has anyone seen any comments on this? Cheers, John.
