The following reply was made to PR kern/119716; it has been noted by GNATS. From: Pete French <petefrench@ticketswitch.com> To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/119716: [acpi] vm_fault when trying to boot 7.0 ACPI on HP dc5750 Date: Tue, 22 Jan 2008 13:23:32 +0000 With the help of John Baldwin on freebsd-stable I traced this a bit closer. Inside madt_probe in /usr/src/sys/i386/acpica/madt.c the code is ttaking the second brank of the 'ifi' statement - i.e. the branch which is for non 2.0 systems. It successfully completes the madt_map_table call, but then crashes when ttrying to access the returned data. Printing out the value of rsdp->RsdtPhysicalAddress on the retrun gives 0x7fec7f40.
