Background: Toshiba Satellite Pro 6100 BIOS Version 1.90 (latest, dated 11 Aug 2003) FreeBSD 6.1-RELEASE, custom kernel(s) APM Suspend/Resume works without trouble on this configuration (*with* USB devices compiled into the kernel). Currently: After reconfiguring my wife's Toshiba Satellite Pro 4600 recently with FreeBSD 6.1-RELEASE and finding ACPI Suspend/Resume appears to work mostly as it should (USB still complains a bit, but it does work OK), I decided to re-visit ACPI on my 6100. The first ACPI suspend attempt on the 6100 with a (new) USB-free kernel appeared to suspend the system OK with "acpiconf -s S3". Lid-open resume on this first attempt returned a corrupted text console that came back OK following an Fn-F5 cycle. Many "g_vfs_done():ad0s2a..." error messages on the text console suggested trouble, however, so "init 6" was issued, which immediately initiated a kernel panic. Following the reboot, I discovered that my /etc/rc.local file was corrupted (truncated) -- darn. A complete "verbose" dmesg(8) output from a subsequent ACPI suspend/resume cycle is posted here: <http://eng.utoledo.edu/~grafe/pub/tsp6100a.dmesg.acpi.txt>; Note that setting "sysctl hw.acpi.video_reset=0" fixed the corrupted text console on this Toshiba. By way of contrast, dmesg(8) output from a working APM suspend/resume is here: <http://eng.utoledo.edu/~grafe/pub/tsp6100a.dmesg.apm.txt>; For completeness, hardware ACPI-related sysctl(8) information is here: <http://eng.utoledo.edu/~grafe/pub/tsp6100a.hwacpi.txt>; And the ASL dump from acpidump(8): <http://eng.utoledo.edu/~grafe/pub/tsp6100a.asl.txt>; Since APM Suspend/Resume is known to work, this is not a show-stopper for me. I have been interested, however, in getting ACPI services to work on this Toshiba. Guidance & direction as to where to look next by list readers and ACPI experts will be appreciated. -- Dr Gary E RAFE: drgerlists at gmail dot com
