Hi, I am running one-day-old -CURRENT: root_at_nucleus:~ # uname -a FreeBSD nucleus 10.0-CURRENT FreeBSD 10.0-CURRENT #51 r245605: Fri Jan 18 11:25:40 EST 2013 root_at_nucleus:/usr/obj/usr/src/sys/NUCLEUS amd64 I attached a MicroSDHC flash card with a MicroSD->USB adapter, and the system crashed with a kernel page fault. I am certain the SDHC card should work, as it works in other FreeBSD machines. kgdb session follows. Please let me know if I can provide further information. Thanks, Glen Script started on Sat Jan 19 10:03:27 2013 root_at_nucleus:/usr/obj/usr/src/sys/NUCLEUS # kgdb kernel.debug /var/crash/vmcore.8 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
