The following reply was made to PR kern/3156; it has been noted by GNATS. From: "\"Doug Burks\"" <dbx@atmos.washington.edu> To: Joerg Wunsch <joerg_wunsch@uriah.heep.sax.de> Cc: FreeBSD-gnats-submit@freebsd.org Subject: Re: kern/3156: Floppy disk copy freezes Date: Mon, 31 Mar 1997 10:27:28 -0800 (PST) Joerg, When I could straight to the floppy disk, the machine totally freezes after about 5-10 seconds. Only a cold boot restarts the machine. [...] Also, you should never, _never_ use the block device for raw file data. When I use the character device for the floppy copy, everything works smoothly. Maybe my setup is the prime example of why one "should never, _never_ use the block device for raw file data." :( As for the original problem, it still exists, but this workaround is certainly quite easy. As for more information, I can't add much. ANY time under ANY conditions whenever I try to copy a large file onto a raw block floppy device, the computer completely freezes after a few seconds. The only other clue I have is that with the TURBO switch off (which cuts the board speed from 75MHz to 25MHz), it freezes almost im- mediately. It sounds like some timing is off somewhere. If no one else is reporting anything like this, maybe my floppy drive is a bit flaky. This operation only fails under 2.2.1, as it worked under 2.1.5 and 2.1.6, though slowed the computer down noticeably. Since this problem no longer prevents me from doing my work, you can do with this report what you will. Doug Burks dbx@atmos.washington.edu
