Write-protected floppy crash

2000-06-06 Thread Oleg Derevenetz
When write-protected floppy mounted in R/W mode, write attempt to this floppy follows kernel panic (dirty buffers) and reboot. Is this correct ? The best way IMO is to always mount write-protected floppies in R/O mode. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe

mmap bug

This small program, running as 'mmap', not 'mmap -u', can hang my machine. Is this a known bug in FreeBSD's kernel, or it is my fantasy ? Thank you for answer. #include stdio.h #include stdlib.h #include sys/types.h #include sys/mman.h #include unistd.h #include fcntl.h #include errno.h
