Please check your kernel config for the following:
MACH_TS72XX must be selected
BLK_DEV_IDE_TSCF must be selected
I'm not sure of exact choices when doing 'make menuconfig', but you
must end up with at least these. Above values are for the 2.6.21-TS
kernel version, later vanilla kernels may be different.
A few other suggestions:
* For debugging, can you boot from NFS? Then you can see if you can
mount the CF. Once you can mount and read/write it with your new
kernel, then you can work on booting from it. For booting, make sure
that the support is built into the kernel, and not as a module.
* 2.6 kernels have mostly switched from /dev/hda devices to scsi
devices /dev/sda. Look through your dmesg to see if the CF is being
detected as sda. If so, you may have to change the kernel boot
command line from root=/dev/hda1 to root=/dev/sda1. I don't know if
that is the case with the 2.6.21-TS kernel or not.
* You might try a later kernel with Matt's patch set (2.6.27.4). I'm
pretty sure that one has the CF showing up as /dev/sda. At least it
has CONFIG_PATA_TS72XX=y and CONFIG_PATA_TS7200_CF=y in the config (in
the scsi transport section).
