Commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") in v6.6 added new code to handle the Power On/Reset Unit Attention (POR UA) sense data. This was in addition to the existing method. When this Unit Attention is received, the driver blocks attempts to read, write and some other operations because the reset may have rewinded the tape. Because of the added code, also the initial POR UA resulted in blocking operations, including those that are used to set the driver options after the device is recognized. Also, reading and writing are refused, whereas they succeeded before this commit.

Applied to 6.14/scsi-queue, thanks!
