Yep, the kernel is layered quite strictly and messages like

are unrelated to the filesystem running on that drive: the ide driver
is running in a separate layer, and just sees arbitrary block IO
requests, not filesystem requests.

The error is a timeout error.  That could be the ide controller, the
cable, or the drive itself failing.  It _might_ be a software
interaction but it looks more like hardware.
