PROBLEM: flaky access to compact flash cards
SYMPTOMS: when reading card under either of two different USB2 card
readers, get intermittent scsi errors. Card reads fine under USB1.1 reader.
KERNEL: 2.6.12.1
DETAILS:
I've been using lexar cards with the jumpshot reader for some time.
Recently I picked up another card that didn't work with the jumpshot.
My machine doesn't do USB2 so I picked up a USB2.0 pci card (ALi-based).
I was having various compatibility issues until I upgraded to 2.6.12.1.
I have two card readers, one is a cheap oriental one, the other is a
Verbatim. Both claim USB2 hi-speed. Both have worked.
Recently I tried reading a card full of pictures. It got part-way
through then gave me an I/O error. "dmesg" gave a bunch of logs like:

I tried again, and this time it gave different errors:

I switch card readers, and got similar behaviour--it read some of the
files, then gave the following:

Finally, I put the card in my old Jumpshot reader, and it read perfectly
with no errors/warnings, and the files (jpegs) do not appear damaged
when viewed.
Anyone have any ideas what's going on?
