I just installed the latest OpenBSD/i386 snapshot on my Aspire One, and if I run "ifconfig ath0 scan", it results in a kernel panic.
Also worth pointing out, if I touch the touchpad at all during the installer, it results in a few lines of "pckbcintr: no dev for slot 1". This also seems to have the annoying side effect that keyboard state changes (e.g., releasing the enter key) go unnoticed for a while, which result in having to restart the installer. The problem only exists when using bsd.rd. Both dmesgs (with stacktrace where appropriate) below. First, bsd(.mp) with the kernel panic after running "ifconfig ath0 scan": OpenBSD 4.5-current (GENERIC.MP) #32: Sun May 10 22:10:12 MDT 2009 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP RTC BIOS diagnostic error 80<clock_battery> cpu0: Intel(R) Atom(TM) CPU N270 @ 1.60GHz ("GenuineIntel" 686-class) 1.60 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,EST,TM2,xTPR real mem = 1060163584 (1011MB) avail mem = 1016750080 (969MB) RTC BIOS diagnostic error 80<clock_battery> mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 10/06/08, SMBIOS rev. 2.4 @ 0xe8e70 (32 entries) bios0: vendor Acer version "v0.3309" date 10/06/2008 bios0: Acer AOA110 acpi0 at bios0: rev 2 acpi0: tables DSDT FACP SSDT HPET APIC MCFG ASF!
