I tried it again with 'set hw.pci.mcfg=0' from boot loader prompt and now it actually finds and attaches the disks as usual. But I do not know if I need 'support for PCI-e memory mapped config access', where it is needed and if it can cause problems later with an RELENG_8 installation if it is disabled like in RELENG_7. I only have one PCIe device, a PCIe graphics card, which is working well with drm.ko / radeon.ko modules and radeonhd driver under RELENG_7. Is it safe to stay with 'hw.pci.mcfg=0' under RELENG_8 for the future? And if so, should the default setting be changed from enabled to disabled for 8.0-RELEASE if it is not yet mature enough and the cause of problems? Looks like several people are affected by this regression. -- Regards
