A UGreen USB3 storage card adapter (model 30333) has stopped working with FreeBSD-current, reporting a stream of (da1:umass-sim1:1:0:0): TEST UNIT READY. CDB: 00 00 00 00 00 00 (da1:umass-sim1:1:0:0): CAM status: SCSI Status Error (da1:umass-sim1:1:0:0): SCSI status: Check Condition (da1:umass-sim1:1:0:0): SCSI sense: NOT READY asc:3a,0 (Medium not present) (da1:umass-sim1:1:0:0): Error 6, Unretryable error (da2:umass-sim1:1:0:1): TEST UNIT READY. CDB: 00 00 00 00 00 00 (da2:umass-sim1:1:0:1): CAM status: SCSI Status Error (da2:umass-sim1:1:0:1): SCSI status: Check Condition (da2:umass-sim1:1:0:1): SCSI sense: NOT READY asc:3a,0 (Medium not present) (da2:umass-sim1:1:0:1): Error 6, Unretryable error in what looks like an infinite loop (there are 4 daX devices on the adapter). The present kernel displaying these errors is FreeBSD 13.0-CURRENT (GENERIC-MMCCAM) #5 main-c255664-g4d64c7243d26: Sat Jan 9 11:27:58 PST 2021 Unplugging the adapter restores normal operation. Rebooting to FreeBSD www.zefox.org 13.0-CURRENT FreeBSD 13.0-CURRENT #3 r361820: Sun Jun 7 22:19:00 PDT 2020 bob@www.zefox.org:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64 exhibits normal behavior, the adapter can be read and written without trouble. As an aside, a Raspberry Pi4 8GB suffers even worse mischief when the adapter is connected, losing communication with the USB root device even after the adapter is unplugged. A power cycle is required to recover. That system is Linux raspberrypi 5.4.83-v7l+ #1379 SMP Mon Dec 14 13:11:54 GMT 2020 armv7l GNU/Linux Since it implements onboard WiFi presumably it has some equivalent to MMCCAM. Might this behavior have anything to do with MMCCAM ? Thanks for reading, bob prohaska
