Just decided to try out the 0907 snapshot of -CURRENT (amd64) and it won't boot off the install CD Thought I would post as much info as I could for interested parties. I have to copy by hand, so I will try to include as much as I can. panic: mutex Giant not owned at /usr/src/sys/cam/cam_xpt.c :4799 This error occurs right after "md0: Preloaded image </boot/mfsroot> .... The motherboard is an Asus P5M2-R, with dual bge ethernets (on mb), a Adaptec 3405 SATA/SAS RAID PCI-e card (aac driver), and has an Intel Q6600 quad core. 4GB of RAM. You will soon see why I included the information on the Adaptec card. This hardware works fine using 6.2-RELEASE p8 -- well, at least i386 does. This system has a modified src/sys/dev/aac which includes the vendor ID info for the 3405/3805 cards and has no problems booting (and running), detecting Adaptec card, etc. I also have a CD with the same snapshot (CURRENT, 0907) in an i386 version (not AMD64) which appears to produce the same error. Upon the panic, the system entered the debugger and I typed "trace" to get the following from AMD64 snapshot: Tracing pid 26 tid 100026 td 0xffffff0002245680 kdb_enter() at kdb_enter+0x31 panic() at panic+0x173 _mtx_assert() at _mtx_assert+0xd6 xpt_release_simq() at xpt_release_simq()+0x27 aac_alloc_commands() at aac_alloc_commands()+0x156 aac_command_thread() at aac_command_thread()+0xe5 fork_exit() at fork_exit+0x12a fork_trampoline() at fork_trampoline()+0xe --- trap 0, rip = 0, rsp = 0xffffffffac6fdd30, rbp = 0 --- Hope this helps someone, Steve
