My application uses SCSI disks of 256, 512, 768, and 1024 sector sizes. It uses the sg_io interface to talk to these devices. As of 2.6.27 if any SCSI disk is attached that has been formatted with a 256 byte sector size, the boot process hangs when it gets to the point of discovering USB devices. 512, 768, and 1024 sector sizes do not seem to trigger this. I have bisected this problem to the following commit: # git bisect good 427e59f09fdba387547106de7bab980b7fff77be is first bad commit commit 427e59f09fdba387547106de7bab980b7fff77be Author: James Bottomley <James.Bottomley@xxxxxxxxxxxxxxxxxxxxx> Date: Sat Mar 8 18:24:17 2008 -0600 [SCSI] make use of the residue value USB sometimes doesn't return an error but instead returns a residue value indicating part (or all) of the command wasn't completed. So if the driver _done() error processing indicates the command was fully processed, subtract off the residue so that this USB error gets propagated.

I have a feeling that this commit is just uncovering another problem. I've attached a dmesg from a working kernel and pointed out where the boot hangs and my SCSI disk light is on solid. Once it turns on solid the only recourse is to recycle power to the disk. The reset button does nothing to it. In fact a second will not even see the device because it is out to lunch. Not even a SCSI bus reset clears what ever has happened to the disk. This does the same thing on a 2.6.34 kernel also. Anything I can do to help, I'm available. Thanks and regards Mark
