I installed 5.7 from http://ftp3.usa.openbsd.org/pub/OpenBSD/5.7/amd64/install57.iso in a Windows Server 2012 R2 Hyper-V VM using the "Legacy Network Adapter". I always get a kernel panic in the de(4) driver during boot. If I remove the legacy NIC from the VM config, then I successfully boot, but obviously with no network access.
What additional information can I provide to help with diagnosis and create a proper bug report? >> OpenBSD/amd64 BOOT 3.28 ... wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) de0 at pci0 dev 10 function 0 "DEC 21140" rev 0x20panic: Non dma-reachable buffer at curaddr 0x107762b70(raw) Stopped at Debugger+0x9: leave Debugger() at Debugger+0x9 panic() at panic+0xfe _bus_dmamap_load_buffer() at _bus_dmamap_load_buffer+0x1b6 _bus_dmamap_load() at _bus_dmamap_load+0x7f tulip_busdma_init() at tulip_busdma_init+0xa0 tulip_attach() at tulip_attach+0x2a4 config_attach() at config_attach+0x1bc pci_probe_device() at pci_probe_device+0x467 pci_enumerate_bus() at pci_enumerate_bus+0xe9 config_attach() at config_attach+0x1bc end trace frame: 0xffffffff81a28e60, count: 0 RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
