I come across some problems of using the cfstix with a 1GB Kingston CF Flash card. After the gumstix was booted, I could mount the card successfully. However, about a few minutes later, I received the following errors:
hdb: no response (status = 0xa1), resetting drive
hdb: no response (status = 0xa1)
ide0 at 0xc4860000-0xc4860007,0xc486000e on irq 49
ide-cs: hda: Vcc = 5.0, Vpp = 0.0
and then I got I/O error while trying to read the filesystem on the card.
