Hello,

the bios was already on AHCI...

That's really bad. I am looking forward to using NetBSD on this laptop
for my production system, and this is a "feature" I would really need.

Look at this:

# sysctl hw.acpi.supported_states
hw.acpi.supported_states = S0 S3 S4 S5

# dmesg | grep pciide0
pciide0 at pci0 dev 3 function 2: vendor 0x8086 product 0x2a46 (rev. 0x07)
pciide0: bus-master DMA support present, but unused (no driver support)
pciide0: primary channel wired to native-PCI mode
pciide0: using ioapic0 pin 18 for native-PCI interrupt
atabus0 at pciide0 channel 0
pciide0: secondary channel wired to native-PCI mode
atabus1 at pciide0 channel 1
Devices without power management support: pciide0

Indeed:

Jan 11 14:00:18  /netbsd: acpi0: entering state 3
Jan 11 14:00:18  /netbsd: Devices without power management support: pciide0
Jan 11 14:00:18  /netbsd: acpi0: aborting suspend
Jan 11 14:04:39  /netbsd: acpi0: entering state 3
Jan 11 14:04:39  /netbsd: Devices without power management support: pciide0
Jan 11 14:04:39  /netbsd: acpi0: aborting suspend
Jan 11 14:04:44  /netbsd: acpi0: entering state 4
Jan 11 14:04:44  /netbsd: Devices without power management support: pciide0
Jan 11 14:04:44  /netbsd: acpi0: aborting suspend

So: No suspend or standby...


Thanks


Pau
