I can not reproduce this with a memory disk image of an msdos floppy (I do not have a floppy on that machine) can you try accessing the floppy without mounting? e.g. can you try using it as a raw device with TAR or something? Maybe it's the floppy driver rather than tehe filesystem. If you can get a coredump and thus a stack backtrace it could be very helpful. thanks On Thu, 30 Aug 2001, Carlo Dapor wrote: > > can you try the same with a "matching" -current? > > I heard that msdosfs is bombing there too. > > (just to confirm this.. if it works there but not with KSE > > then we have work to do :-) > > I build and run a kernel just before applying the patches, that was able to > mount the partition and 'accepted' reads/writes/deletes/create directories etc. > for a good three to four hours. > > As I stated earlier, the kse-patched kernel produced this: > > > Fatal trap 12: page fault while in kernel mode > > fault virtual address = 0x4 > > fault code = supervisor read, page not present > > instruction pointer = 0x8:0xc11fa49a > > stack pointer = 0x10:0xca36aa70 > > frame pointer = 0x10:0xca36ae20 > > code segment = base 0x0, limit 0xfffff, type 0x1b > > = DPL 0, pres 1, def32 1, gran 1 > > processor eflags = interrupt enabled, resume, IOPL = 0 > > current process = 24854 (mount_msdosfs) > > trap number = 12 > > panic: page fault > > syncing disks... panic: bdwrite: buffer is not busy > > Uptime: 15h12m23s > > Automatic reboot in 15 seconds - press a key on the console to abort > > --> Press a key on the console to reboot <-- > > Right now, I am applying src-cur.4939.gz, after having reversed the KSE > patches.
