https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231760 --- Comment #12 from Rajesh <rajfbsd@gmail.com> --- (In reply to John Baldwin from comment #11) Yes, Address 0xb to the specified PCI device is the last pci_cfgregread call what I see before system reboots. I see "acpi0: Power Button (fixed)" messa= ge in working case(mcfg=3D0) after this particular read. Regarding acpidump,=20 1) Without "-t" I don't see anything on stdout. 2) With "-t" I can see the RSD PTR, XSDT, FACP and FACS tables printed in s= aid order and just hangs after that (I will just clarify what details I can sha= re and paste those tables here). If I leave the hang as such for a while, syst= em reboots. But, one thing I see is DSDT=3D0 in the FACP block. Is that valid? Also, Is there anything specific which I need to check regarding the BIOS? --=20 You are receiving this mail because: You are the assignee for the bug.=
