[Yaird-devel] Bug#354247: yaird error: no link to block device in ... (fatal)

Package: yaird
Version: 0.0.12-2bpo1
Severity: Normal

Unless something changes before 2.6.16 is released, the sysfs entry for my
ATA controller isn't discovered as sysfs information has been changed, at
least for my ATA controller.

I've included a patch that resolves the immediate issue for me, but it's a 3
am kludge. :)

Thanks.
