With OpenBSD 5.2, I had no issue doing suspend and hibernate: when I closed the lid, it suspended, when I hit Fn+F12 the BIOS took over, with it's own pretty text interface, and hibernated the system. iwi(4) also worked flawlessly with suspend/hibernate. Fast forward to upgrading to "5.5" with ACPI: setting machdep.lidsuspend=1 allows the system to suspend when I close the lid, but iwi(4) is broken upon resume (iwi0: could not load boot firmware) and Fn+F12 or ZZZ leaves me with a blank screen and an eternal flashing moon LED (swap is RAM + 1GB). If I disable ACPI in UKC, which is enabled by default, everything works as it did in 5.2 with the exception of hibernate which behaves as if ACPI was enabled.
Any recommendations on how to fix? Thanks. dmesg with ACPI enabled (default): OpenBSD 5.5 (GENERIC) #276: Wed Mar 5 09:57:06 MST 2014 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) M processor
