I got an old 720KB dos floppy and wanted to try it with my x86_64 2.6.17-rc= 3 kernel. Mounting it Kernel says: FAT: invalid media value (0x44) VFS: Can't find a valid FAT filesystem on dev fd0 I tried it on my pentium with the same kernel (i386, of course), and it wor= ks. Mounted as vfat. All files there. No errors. On the x86_64, noting. Formatting a 1.44MB disk as 1.44MB works. The integrity check on kfloppy works too. Formatting a 1.44MB disk as 720KB works. But checking integrity does not. Kfloppy says that theres an error while low-level format on track 0. Kernel says: end_request: I/O error, dev fd0, sector 0 floppy0: Getstatus times out (50) on fdc 0 floppy driver state ------------------- nowC15028397 last interruptC15028397 diff=3D0 last called handler=FFffffff8= 0360d1d timeout_message=3Dfloppy start last output bytes: 2 90 4315027201 9 90 4315027201 50 90 4315027201 f6 90 4315027201 f 80 4315027600 0 90 4315027600 45 91 4315027600 8 81 4315027605 4d 80 4315027625 0 90 4315027625 2 90 4315027625 9 90 4315027625 50 90 4315027625 f6 90 4315027625 4d 80 4315027998 4 90 4315027998 2 90 4315027998 9 90 4315027998 50 90 4315027998 f6 90 4315027998 last result at 4315027998 last redo_fd_request at 4315027998 40 10 0 1 4 7 2 statusP fdc_busy=3D1 fd_timer.function=FFffffff80362b84 timer_function=FFffffff8036301d expires&01 nowC15028397 cont=FFffffff804b2b40 current_req=0000000000000000 command_status=3D-1 floppy0: get result error.
