It's the question I want to ask next. Thanks. It seems worthwhile to upgrade
CATS bootloader to ABLE. I have v206 image at hand.

The DMA issue may be removed since transfer error symptom might be
caused by ARM (Footbridge?) dependent code.

tlp0 was found complete useless for 2.1 and 3.0 kernel. I hooked sip0
instead. It's somehow relieving to see that USB is quite stable. USB
keyboard, USB bar code scanner, SCSI HD disguise memory disk,
and USB serial adaptor work well for me.
And here is today's special. ARM Atheros WLAN can work well for
