Heh, sounds like it's a "shutdown -h now", which is more or less what I saw on the screen the last time I tried. > S4 is suspend to disk.

The lack of a hibernation partition is indicated the value of hw.acpi.s4bios? That's interesting. I will try a hibernation partition. From the sounds of it, it sounds like the best suspend strategy. I now have a clear milestone which will indicate I'm good to go with hibernation. > To get S3 (suspend to RAM) to work, I'd suggest building a kernel > without SMP or APIC.

Upon rechecking, I see I did a make buildkernel KENCONF=LAPTOP.... and KENCONF != KERNCONF.... After compiling the correct kernel (the above worked on GENERIC by default), I no longer have the uhub issues. The existing issues after a resume are: - blinking cursor at top left (I'll try killing moused in /etc/suspend and starting it again in /etc/resume) - em0 is dead upon resume (I'll try killing dhclient, and starting it again, as well as setting). I keep getting laptop kernel: em0: The EEPROM Checksum Is Not Valid laptop kernel: em0: Unable to initialize the hardware At boot time, this problem is avoided with the following entry in /boot/loader.conf hw.pci.allow_unsupported_io_range="1" Any ideas how to set that upon resume? -- Dan Langille : http://www.langille.org/ BSDCan - http://www.bsdcan.org/
