SysRq : Emergency Remount R/O

Remounting device 03:08 ... OK

Remounting device 03:05 ... nothing to do
Remounting device 03:0a ... R/O
Done.

03:06, 03:08, and 03:09 are ext3.
03:05 is FAT32.
I don't know what 03:0a is (root device ?).

>From the documentation:

'u'     - Will attempt to remount all mounted filesystems read-only.

But why didn't it do it for the FAT32 partition ?

# mount -o remount,ro /mnt/vfat
...
/dev/hda5 on /mnt/vfat type vfat (ro)

So, it works fine manually.

This is on 2.4.25.
