I am running diablo from external card in my n810.

this is the fdisk output:
sudo sfdisk -l /dev/mmcblk1

Disk /dev/mmcblk1: 243200 cylinders, 4 heads, 16 sectors/track
Units = cylinders of 32768 bytes, blocks of 1024 bytes, counting from 0

Device Boot Start End #cyls #blocks Id System
/dev/mmcblk1p1 0+ 16383 16384- 524287+ 6 FAT16
/dev/mmcblk1p2 16384 239103 222720 7127040 83 Linux
/dev/mmcblk1p3 239104 243199 4096 131072 82 Linux swap / Solaris
/dev/mmcblk1p4 0 - 0 0 0 Empty


And the mount info showed this after start from external card before:

/dev/mmcblk1p2 on / type ext3 (rw,noatime,data=ordered)

But, today, after I turn on Swap in pbeasy.
the mount info changed to this.

/dev/mmcblk0p2 on / type ext3 (rw,noatime,data=ordered)

the device changed from /dev/mmcblk1p2 to /dev/mmcblk0p2. but the fdisk info does not change.

And, the system runs OK till now.
So, guys, what's the problem here?

There is a bug that sometimes switches internal and external card devices. I think this is what happened.

Oh, thanks. Is there a workaround for this?
