Re: ide-scsi bug hard locks machine

[Jason Thomas <jason@topic.com.au>]

so after some coaching, below should be some useful information.

I have a liteon 48x cd burner connected to a promise controller using
ide-scsi, this currently works fine on 2.5.52. I think this also
happened with 2.5.54 and I gave up on that one. The output below is from
2.5.56.

Thanks
