[Bug 37163] Re: EFI-support in kernel causes I/O errors with iPods

[Ylan]

I can report the same error while pluggin in my iPod directly into my
laptop, on either one of the two ports. I haven't tried writting to it,
just reading (this my iPod has not been corrupted yet). dosfsck reports
no errors on the iPod (System log appropriate entries are at the
bottom).

Hardware:
- Sony Vaio PEG-505exp
- iPod 20Gb click-wheel (no photo), windows formatted
Software:
- Ubuntu Dapper

Is it possible for someone to post to one of the repositories (or
elsewhere) the kernel compiled with the workaround? It would make it
much easier for users like me to get a quick fix without having to build
the kernel ourselves (which is, quite frankly, way over my head).

Thanks,
