Subject: [PATCH] esp: Handle CMD_BUSRESET by resetting the SCSI bus mainline
|
|
inclusion commit c6e51f1bb28ed762d2039c063cbb71a8ad29762d category: bugfix
|
|
|
|
---------------------------------------------------------------
|
|
|
|
Per investigation on the linked ticket, SunOS issues a SCSI bus reset
|
|
to the ESP as part of its boot sequence. If this ESP command doesn't
|
|
cause devices to assert sense flag UNIT ATTENTION, SunOS will consider
|
|
the CD-ROM device to be non-compliant with Common Command Set (CCS).
|
|
In this condition, the SunOS installer's early userspace doesn't set
|
|
the installation source location to sr0 and the miniroot copy fails.
