Hello=2C We are upgrading our ESX to Hyper-V=2C and all our virtual FreeBSD will b= e running on Hyper-V. For our POCs=2C we are testing all the releases of the 10.0 RCxx. I installed 10.0 RC5 on a new virtual machine running on Hyper-V. I svn checkout /base/stable/10 Without modifying neither the kernel nor the src.conf=2C I buildworld=2C bu= ildkernel=2C installkernel=2C installworld. After booting I had a kernel panic on attaching the storvsc. I don't remember having this panic on older RCs of the 10.0 Here is the bt (OCRed): cpuid =3D 0 KDB: stack backtrace: #0 0xffffffff808d1670 at kdb_backtrace+0x60 #1 0xffffffff80899045 at panic+0x155 #2 0xffffffff80c73672 at trap_fatal+0x3a2 #3 0xffffffff80c73949 at trap_pfault+0x2c9 #4 0xffffffff80c730d6 at trap+0x5e6 #5 0xffffffff80c5a462 at calltrap+0x8 #6 0xffffffff80885ff0 at __mtx_unlock_sleep+0x60 #7 0xffffffff80885b4a at unlock_mtx+0x2a #8 0xffffffff808a1c4e at _sleep+0x18e #9 0xffffffff802dc2be at cam_periph_runccb+0x9e #10 0xffffffff80cfe6f4 at storvsc_attach+0x6d4 #11 0xffffffff808c89e2 at device_attach+0x3a2 #12 0xffffffff80d0311b at hv_vmbus_child_deuice_register+0xdb #13 0xffffffff80d01a33 at vmbus_channel_process_offer+0x133 #14 0xffffffff80d01576 at work_item_callback+0x26 #15 0xffffffff808df406 at taskqueue_run_locked+0xe6 #16 0xffffffff808dfc88 at taskqueue_thread_loop+0xa8 #17 0xffffffff8086b11a at fork_exit+0x9a Uptime: 1s Automatic reboot in 15 seconds - press a key on the console to abort I tried to add hw.ata.disk_enable=3D1 in /boot/loader.conf without help. Thank you for any advice. Best regards =
