Hi Mike,

Sorry, but you'll have to bear with me here as this is the first TS
product I've used. You mentioned before that "everything was working"
in fastboot mode, where fastboot = type "exit" from serial shell and
boot to onboard flassh (/dev/mtdblock3) (i.e, remove SD card). The
linuxrc-fastboot script makes no mention of either tsuart1.ko or
tsuart7800.ko, but ls -la /dev/ttts* gives:

crw-r--r--  1 root root 234,  1 Dec 19 20:22 /dev/ttts0
crw-r--r--  1 root root 234,  2 Dec 19 20:22 /dev/ttts1
crw-r--r--  1 root root 234,  3 Dec 19 20:22 /dev/ttts2
crw-r--r--  1 root root 234,  4 Dec 19 20:22 /dev/ttts3
crw-r--r--  1 root root 234,  5 Dec 19 20:22 /dev/ttts4
crw-r--r--  1 root root 234,  6 Dec 19 20:22 /dev/ttts5
crw-r--r--  1 root root 234,  7 Dec 19 20:22 /dev/ttts6
crw-r--r--  1 root root 234,  8 Dec 19 20:22 /dev/ttts7
crw-r--r--  1 root root 234,  9 Dec 19 20:22 /dev/ttts8
crw-r--r--  1 root root 234, 10 Dec 19 20:22 /dev/ttts9

and lsmod produces: 

Module                  Size  Used by
tssdcard               28352  0 
ts7800                  3696  2 

So, while I can see the devices, the modules clearly aren't being
loaded, even from the default flash. The only place the modules are on
the flash are under /lib/modules/... and these have the "old" md5sums
as mentioned above.

So, I'm not so sure that the ports are working correctly from the
factory flash (I haven't reflashed). Any thoughts on how we can get
this fixed?
