Hello stable@,
system: 11-stable r313553
In the kernel there is an option for scsi delay. Is there also one for
usb? Perhaps not in the kernel but elsewhere. I can't find it.
The problem is seen especially where the bootable device is usb. The
boot process starts and dumps me at mountroot where I wait for a short
time until the usb stick is properly detected (bright white writing at
the console). The usb stick is plugged into a usb3 port. For example:

Then this happens:
(probe0:umass-sim0:0:0:0): INQUIRY. CDB: 12 00 00 00 24 00
(probe0:umass-sim0:0:0:0): CAM status: CCB request completed with an error

da0: 30176MB (61800448 512 byte sectors)
da0: quirks=0x3<NO_SYNC_CACHE,NO_6_BYTE>
so now at the mountroot prompt I enter ufs:/dev/da0p2 (which is a value
that mountroot already had) and carry on booting:

The same sort of thing happens on an 11-stable r313043 desktop, only
this time I'm not booting from usb. The system comes up, I get a login
prompt, then five or ten seconds later usb wakes up having detected the
usb3 external HD.
How can I fix this?
thanks,
