[ Please CC me, I'm not subscribed to freebsd-acpi ] Hi, I experienced some strange problems with ACPI or APM on my IBM Thinkpad T43 (Type 2668) and FreeBSD 6.0-BETA. To enable suspend2RAM I tried the following things: o ACPI If ACPI is enabled, suspend work without problems. If I try to resume the machine freezes and the following message is displayed: ioapic_suspend: not implemented! ioapic_suspend: not implemented! [...] ioapic_suspend: not implemented! acpi_bus_number: can't get _ADR [freeze] If I set hint.apic.0.disabled to 1 the laptop resumes fine. Now the strange thing: Everything is incredible slow. Normal working/typing is nearly impossible. Why? o APM I disabled ACPI and enabled APM to get Suspend working. With the GENERIC kernel [2] Suspend/Resume is working fine. But I can't suspend while X is running, I have to switch back to console. If I compile a custom kernel [3] to get rid of some debugging stuff Suspend with APM isn't working anymore!? Did I something wrong? Maybe it's a problem with the builtin ICH6M SATA Controller? For further information: My dmesg [1], the GENERIC kernel config [2], my own kernel config [3] and the output of pciconf -l -v [4].
