https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211895 --- Comment #10 from Aleksander Alekseev <afiskon@devzen.ru> --- Ok, here are a few updates on this issue. 1. I solved all issues regarding entering KDB and writing kernel core dumps. Now I can provide really any debug information you might need. In case anyo= ne is interested the problem with KDB was that for some reason RC and RELEASE builds of FreeBSD don't have DDB option in GENERIC kernel by default. To wr= ite kernel dumps one needs a swap partition and dumpdev value in /etc/rc.conf pointing to this partition. A good explanation of how UFS partition could be shrinked to create a swap partition: https://www.reddit.com/r/freebsd/comments/4ph4xu/shrink_ufs_root_fs/ 2. The problem _does_ exist in 12.0 as well (I tested on r305736). usbconfig doesn't hang, but keyboard still doesn't work. Neither does any other USB device (flash drives, etc). Here is how dmesg looks like: http://afiskon.ru/s/67/ba7648265f_usb120.jpg As you may see there is no more infinite loop that calls usb_alloc_device a= nd uhub_reattach_port - they are called only one. But no other USB device coul= d be connected afterwards (see "giving up" errors). 3. Here are core.txt.0 and vmcore.0 created manually after issue was reproduced: http://afiskon.ru/s/aa/0e02bb563b_core.txt.0.txt http://afiskon.ru/s/7a/d529b2c2d7_vmcore.0.tgz Is there anything else I can do to help? --=20 You are receiving this mail because: You are the assignee for the bug.=
