FFS Panic with CF Card

["Harald Schmalzbauer" <Harald.Schmalzbauer@wearix.com>]

Hello all,

I'm about to do a Soekris router. I bought a CF-IDE adaptor which simulates
a ZIP-100, so I can Hot-Plug the CF.
OpenBSD (3.1) recognizes this adaptor as "atapiscsi" and I can access the CF
as sd0. But I always get the following error:

sd0(atapiscsi1:0:0): Check Condition on opcode 0x5a
    SENSE KEY: Illegal Request
    ASC/ASCQ: Illegal Field in CDB

And when I try to copy lots of files the whole system panics.

panic: ffs_clusteralloc: map mismatch

Here the trace:

What's going wrong?

I also have very mysterious behaviour of the CF. Sometimes the date of
written files is completely wrong, sometimes the size is negative and an
astronomical number.

Any help is highly appreciated.

Best regards,
