Ext3 problems with 2.5.69

[Maciej Soltysiak]

Hi,

having opened in mc one panel with an ext3 filesystem and a vfat fs
on a usb flash memory device, mc froze and this is what i got in the
kern.log:

I can't kill mc that caused it, and i can't unmount the fs to check it, so
i will reboot and try to fix it and see if there were any errors on the
fs, although the fs is clean as tune2fs -l says:
Filesystem magic number:  0xEF53
Filesystem revision #:    1 (dynamic)
Filesystem features:      has_journal dir_index filetype needs_recovery sparse_super
Default mount options:    (none)
Filesystem state:         clean

Regards,
Maciej
