It looks as if things are somewhat altered, but not really improved, after updating to FreeBSD pelorus.zefox.org 13.1-STABLE FreeBSD 13.1-STABLE #24 stable/13-n249989-b85d0d603c5: Sat Mar 12 17:47:19 PST 2022 bob@pelorus.zefox.org:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64 on the Pi3 with USB root disk (hdd, not ssd). After reboot the machine answered around 30 % of incoming pings and sometimes responded to ssh login attempts. At least once the login attempt was successful, even with no outgoing ping process running. That seems like progress. With an outgoing ping running it's possible to ssh into the machine, with a highly variable delay for the password prompt. Unfortunately, new console errors are appeared: bob@pelorus:~ % (da0:umass-sim0:0:0:0): WRITE(10). CDB: 2a 00 1f ea a3 c0 00 00 40 00 (da0:umass-sim0:0:0:0): CAM status: SCSI Status Error (da0:umass-sim0:0:0:0): SCSI status: Check Condition (da0:umass-sim0:0:0:0): SCSI sense: ABORTED COMMAND asc:47,3 (Information unit iuCRC error detected) (da0:umass-sim0:0:0:0): Retrying command (per sense data) The error message repeated at intervals, seemingly linked to disk activity, with the machine running out of retries after starting buildworld. That seems like progress in reverse 8-) Reverting to 13-n249985-dd6c1475a63: Fri Mar 11 18:06:31 PST 2022 permitted recovery, with the old problems attendant. -current now has some usb testing tools: root@www:/usr/src # ls tools/tools/usbtest Makefile usb_control_ep_test.c usb_msc_test.c usbtest.c Makefile.depend usb_modem_test.c usb_msc_test.h usbtest.h Is there any guidance on what they do? I couldn't find a man page. Thanks for reading, bob prohaska
