Hi,
With kernel 2.4.12 I am having problems with mount hanging.
oscar% mount /fuji oscar% cd /fuji oscar% ls dcim oscar% cd oscar% umount /fuji oscar% mount /fuji mount: wrong fs type, bad option, bad superblock on /dev/sda1, or too many mounted file systems oscar% mount /fuji
and ps shows
oscar% ps -efl | grep mount 100 D root 876 793 0 69 0 - 368 down 19:28 pts/1 00:00:00 mount /fuji 000 S ed 943 886 0 71 0 - 341 pipe_w 19:31 pts/2 00:00:00 grep mount
With 2.4.10 and below I would get the wrong fs message too. The next mount would work. One interesting thing. The second mount will work if the media has not changed...
mount /fuji umount /fuji mount /fuji
will work but
mount /fuji umount /fuji <change media> mount /fuji
hangs.
kern.log shows:
Oct 13 19:28:31 oscar kernel: usb-uhci.c: interrupt, status 2, frame# 1147 Oct 13 19:28:31 oscar kernel: I/O error: dev 08:01, sector 0 Oct 13 19:28:31 oscar kernel: FAT: unable to read boot sector Oct 13 19:28:31 oscar kernel: VFS: Disk change detected on device sd(8,1) Oct 13 19:28:31 oscar kernel: SCSI device sda: 131072 512-byte hdwr sectors (67 MB) Oct 13 19:28:31 oscar kernel: sda: Write Protect is on Oct 13 19:28:31 oscar kernel: sda: sda1
The device is a usb smartmedia reader using the sddr-09 support.
