Description Marc Benstein 2004-10-31 04:16:40 UTC

I can't mount what I believe is a valid FAT partition. (It works fine in ac-source-2.6.9-a2)

ac-sources-2.6.9-a5 .config:
# DOS/FAT/NT Filesystems
CONFIG_FAT_FS=m
CONFIG_VFAT_FS=m
CONFIG_FAT_DEFAULT_CODEPAGE=437
CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"

I noticed ac5 patch made some changes in linux.vanilla-2.6.9/fs/fat/inode.c

dmesg shows:
FAT: invalid first entry of FAT (0xffffff8 != 0xffffff8)
VFS: Can't find a valid FAT filesystem on dev hda5.
