Re: [BUG][2.5.49 SCSI]Duplicate Proc Entries for SCSI

["Rusty Lynch" <rusty@linux.co.intel.com>]

Ah, forgot about that.

I only see this on my box at home (that I can't ssh to from work).  I just
now checked out my development box that has SCSI drives on it and it does
not exhibit the problem.

I will try what you suggested on the offending box after I go home tonight.
