Here is the weekly report. 1. Got my new powerful PC which is powerd by the new intel haswell arch and installed freebsd 10.0 current amd64 20130623-r252101. 1.1 found freebsd xhci driver bug, need to pass hw.usb.xhci.xhci_port_route=-1 to workaround this issue. Otherwise no any usb port will work 1.2 found one fs bug? kernel will complain as the following when shutdown or remove files. lock order reversal: 1st 0xfffffe0003582418 ufs (ufs) @ /usr/src/sys/kern/vfs_mount.c:1236 2nd 0xfffffe0003629240 devfs (devfs) @ /usr/src/sys/kern/vfs_subr.c:2099 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffff80002335b0 kdb_backtrace() at kdb_backtrace+0x39/frame 0xffffff8000233660 witness_checkorder() at witness_checkorder+0xd4f/frame 0xffffff80002336f0 __lockmgr_args() at __lockmgr_args+0x6f2/frame 0xffffff8000233820 vop_stdlock() at vop_stdlock+0x3c/frame 0xffffff8000233840 VOP_LOCK1_APV() at VOP_LOCK1_APV+0xf5/frame 0xffffff8000233870 _vn_lock() at _vn_lock+0xab/frame 0xffffff80002338e0 vget() at vget+0x70/frame 0xffffff8000233930 devfs_allocv() at devfs_allocv+0xfd/frame 0xffffff8000233980 devfs_root() at devfs_root+0x43/frame 0xffffff80002339b0 dounmount() at dounmount+0x2d7/frame 0xffffff8000233a20 vfs_unmountall() at vfs_unmountall+0x61/frame 0xffffff8000233a50 kern_reboot() at kern_reboot+0x548/frame 0xffffff8000233ac0 sys_reboot() at sys_reboot+0x58/frame 0xffffff8000233ae0 amd64_syscall() at amd64_syscall+0x265/frame 0xffffff8000233bf0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xffffff8000233bf0 --- syscall (55, FreeBSD ELF64, sys_reboot), rip = 0x40ecdc, rsp = 0x7fffffffd6d8, rbp = 0x7fffffffd7c0 --- 2. tried bhyve on the haswell platform, everything seems fine. 3. read the ahci datasheet again Thanks
