https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231760 --- Comment #9 from John Baldwin <jhb@FreeBSD.org> --- That is really weird to be reading 1 byte of 0x24-0x27. 0x24 is a BAR and nothing should be reading individual bytes of that. Can you get a stack tr= ace for a read of register 0x24 with size 1 (kdb_backtrace() should print out a stack trace)? Given that that is right after ACPI registers its interrupt, I wonder if it= 's something weird in the DSDT itself doing the register accesses? Providing = the acpidump might be useful as well if the stack trace ends up in ACPI. --=20 You are receiving this mail because: You are on the CC list for the bug.=
