[1] The SCSI error on 2.6.13-rc3-mm1 that I found:

echo -n 1 > /sys/.../hostA/targetA:B:C/A:B:C:D/delete
still works. I think.
And (again, I think) this same problem exists with 2.6.11 as well.
At least, I wasn't able to remove-single-device even once (I discovered
this mechanism only recently, haven't tried it with other kernels).
As such, since the same underlying functions are called by hotplugging,
you will only be able to remove a disk from a device once before it
fails, until this error is fixed. I'll look into it as well.
