https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236838 --- Comment #6 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to longwitz from comment #5) I think it is not the 0xce register read which causes the hang, but the need to map very large (255MB) region by chomping from virtual_avail which causes the breakage. You can recheck this by keeping your debugging printfs but reverting the removal of the case line. You dmesg shows the ""PCIe: Memory Mapped configuration base @..." line so the memory-mapped config access method works, and this is what I looked for when asking for dmesg. Please try the attached patch, if my understanding is right, it should be the proper fix. -- You are receiving this mail because: You are the assignee for the bug.help
