Sorry about the problem. Can you try this patch?

Thanks, I applied the patch manually against the Debian 2.6.27 kernel
source at http://kernel-archive.buildserver.net/ and after starting the
patched kernel, the eata module loaded successfully. I mounted the
filesystems on the attached scsi disk and ran ls -alR on all filesystems
successfully.

As with 2.6.22 kernels gnu fdisk had problems with the scsi drive, but
cfdisk and sfdisk were ok:

Thanks very much for the rapid response to this bug report!
