I have a new TS-7400 128MB, OP-BBRTC, TS-DC420-ENC.
The 512MB SD dev card boots fine. I dd the card to a
A-Data 2GB card and resize the 3rd partition, it will
not boot.

The linuxrc script fails to load the sdcard driver!

I manually "insmod -q -f /sdcard.o dmaenable=1" the driver loads.
(dmesg indicates 3994624 sectors, stcard0a: p1 p2 p3)

I now cannot successfully "mount -o ro /dev/sdcard0/disc0/part3 /mnt/root"
I get Invalid argument.

(dmesg says VFS: Can't find ext2 filesystem on dev sdcard0(254,3).

ls /dev/sdcard0/disc0 shows 254,3 as part3.

(dmesg also indicates yaffs: dev is 65027 name is "fe:03")

"dd if=/dev/sdcard0/disc0/part3 of=/dev/null count=256" works fine.

busybox fdisk indicates sector size of 1024?  This same card on my
linux desktop fdisk indicates 512 byte sectors.

I there a new sdcard.o? Mine has a filesize of 19396. I see all kinds
of sdcard.o file sizes in the various places of the TS ftp site.

David.
