Hi Alexander, Due to personally reason, I started to work on my project from June 24. 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
