[-- Attachment #1 --] Hi all, Need you help regarding an urgent issue where we are observing an issue with Freebsd stable/12. The DATA0/DATA1 are out of sync with respect to EP and the system experiences the READ(10) errors. The READ(10) error recovers with in couple of retries most of the times but few cases we have observed that the read retries gets exhausted and system moves to unusable state (continuous g_vfs_done() errors) . We are using Junos but the xhci driver etc.. are all pristine stable 12 drivers no Juniper specific changes. This issue was never observed with Linux kernel 5.4.2 on the same HW. Errors Seen on console (da0:umass-sim0:0:0:0): READ(10). CDB: 28 00 00 28 cf 28 00 00 40 00 (da0:umass-sim0:0:0:0): CAM status: CCB request completed with an error (da0:umass-sim0:0:0:0): Retrying command, 3 more tries remain (da0:umass-sim0:0:0:0): READ(10). CDB: 28 00 00 28 cf 28 00 00 40 00 (da0:umass-sim0:0:0:0): CAM status: CCB request completed with an error (da0:umass-sim0:0:0:0): Retrying command, 2 more tries remain FreeBSD/arm (Amnesiac) (ttyu0) login: I can share the USB traces taken at the USB device if required.
