Hello List,

i am booting a linux box via NFS. 
When it boot it with a 2.4.32 kernel i cCAN mount my compact flash drive
hda.

If i boot a 2.6.16 kernel i CAN NOT.


hdaX is ext3 and ext3 is compiled into the kernel.
Am i missing a kernel option?

More infos:

/dev/hda1 is apparently in use by the system; will not make a filesystem
here!


Attachted is my kernel config of the 2.6.16 kernel.

Do you need more infos?

Try running

$ grep /dev/hda /etc/mtab
$ grep /dev/hda /proc/mounts

The errors from mkfs.ext3 would normally indicate a line containing
/dev/hda in /etc/mtab.
