To my surprise, acpi-S3 seems to work in general on my "new" haswell desktop. Just the NIC (i217) wasn't working after resume. So I wanted to issue a D3-D0, which I thought could be done by 'devctl detach/attach'. The following panic happened after 'devctl detach' – unfortunately swap partition (3G) again too small, so transcribed from photo: Stopped at kdb_enter+0x3b: movq $0,kdb_why Tracing pid 39575 tid 102130 td 0xfffff801a84ff580 kdb_enter() vpanic() panic() _sx_assert() at _sx_assert+0xb2/frame 0xfffffe009ecb3460 e1000_acquire_swflag_ich8lan() at e1000_acqire_swflag_ich8lan+0x36/frame 0xfffffe009ecb34a0 e1000_phy_hw_reset_generic() at e1000_phy_hw_reset_generic+0x2d/frame 0xfffffe009ecb34d0 e1000_phy_hw_reset_ich8lan() at e1000_phy_hw_reset_ich8lan+0x6a/frame 0xfffffe009ecb3500 em_if_detach() at em_if_detach+0x22/frame 0xfffffe009ecb3540 iflib_device_deregister() at iflib_device_deregister+0x25e/frame 0xfffffe009ecb3590 device_detach() at device_detach+0x167/frame 0xfffffe009ecb35d0 devctl2_ioctl() at devctl2_ioctl+0x53b/frame 0xfffffe009ecb36a0 devfs_ioctl() at devfs_ioctl+0xcb/frame 0xfffffe009ecb36f0 VOP_IOCTL_APV() at VOP_IOCTL_APV+0xd9/frame 0xfffffe009ecb3720 vn_ioctl() at vn_ioctl+0x124/frame 0xfffffe009ecb3830 devfs_ioctl_f() at devfs_ioctl_f+0x1f/frame 0xfffffe009ecb3850 kern_ioctl() at kern_ioctl+0x2b9/frame 0xfffffe009ecb38b0 sys_ioctl() at sys_ioctl+0x168/frame 0xfffffe009ecb3980 amd64_syscall() at amd64_syscall+0x28c/frame 0xfffffe009ecb3ab0 fast_syscall_common() at fast_syscall_common Shall I try to reproduce for getting a core file?
