Here's the first one to track (not the first one I keep seeing): In this case a micro SD card on da3 did not show up with partitions anymore; the da1 on the same card reader still worked. Unplugging the card reader checking on USB in order to reset it gave me this: # usbconfig load: 0.27 cmd: usbconfig 61812 [USB config SX lock] 1.61r 0.00u 0.00s 0% 2120k mi_switch+0xc1 sleepq_catch_signals+0x3d1 sleepq_wait_sig+0x9 _sx_xlock_hard+0x451 usbd_enum_lock_sig+0xa1 usb_ref_device+0x221 usb_open+0x106 devfs_open+0x145 VOP_OPEN_APV+0x1c vn_open_vnode+0x1eb vn_open_cred+0x3b7 kern_openat+0x248 amd64_syscall+0x119 fast_syscall_common+0xf8 "can ^c" xhci on a Kaby Lake system. Neither the other USB3 not the USB-C port detect anythign new plugged in currently. Not tried to disable enumeration yet. Had unplugged an external mass storage on USB3/da4 yesterday and not used t= he still plugged-in reader since. Was camcontrol ejected da4. --=20 You are receiving this mail because: You are the assignee for the bug.=
