Setting debug.acpi.disable=hostres did not work. Strange thing is that ath0 is now at mem 0x88000000-0x8800ffff for both working and non-working kernels (with and without debug.acpi.disable=hostres). ath0 still doesn't attach, but it seems funny that the memory address changes. These are all soft reboots, not hard reboots, after a working kernel. All the information you requested is here: http://people.freebsd.org/~deischen/ath/ There are verbose boots and devinfo -u/-r output for the working kernel and the non-working kernel (with and without debug.acpi.disable=hostres). Anything else you'd like me to try? -- DE
