--- Comment #8 from John Baldwin <j...@freebsd.org> --- Created attachment 248936 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=248936&action=edit fix.patch Please try this patch. Looking at the dmesg, the address was translated incorrectly. It matches this range which requires no translation: pcib0: PCI addr: 0x10100000000, CPU addr: 0x10100000000, Size: 0x7f00000000, Type: memory (PCI addr == CPU addr), but it was matching on the wrong range and translating the address as if it belonged to the first range: pcib0: PCI addr: 0x0, CPU addr: 0x10010000000, Size: 0x10000, Type: I/O port The code I changed in commit d79b6b8ec267 expected the end to be >= start, and the end value of 0 in the old code violated this assumption. -- You are receiving this mail because: You are the assignee for the bug.
