Subject: Re: Scsi_bus_resume+0x0/0x90 returns -5 when resuming from s3 sleep

I retried on 6.5 rc3 without the Nvidia drivers and still received the 
same error and going to try for the patch next but got a malformed patch 
error on line 6 for the first patch for libata-scsi.c. The other two 
seem to go through just fine however.

Also the bugzilla link is similar to what I have but the disk doesn't 
disappear, comes back but just takes awhile to come back out of sleep mode.
