6.2-RC: Problem with SATA on ASUS Vintage AH-*1*

[Bruce M. Simpson]

Hello,

The model of this box is actually the ASUS Vintage AH-1, sorry for my error!
A niggling annoyance present on this machine is that the on-board serial 
port defaults to COM2 settings, not COM1, however this may be changed in 
the BIOS.

Here is an excerpt from dmesg which I managed to capture after fixing this:
%%%
atapci2: <AcerLabs M5287 SATA150 controller> port 
0xec00-0xec0f,0xe880-0xe887,0xe800-0xe80f,0xe480-0xe487,0xe400-0xe41f 
mem 0xfebff800-0xfebffbff irq 21 at device 31.1 on pci0
atapci2: Reserved 0x20 bytes for rid 0x20 type 4 at 0xe400
ioapic0: routing intpin 21 (PCI IRQ 21) to vector 53
atapci2: [MPSAFE]
atapci2: Reserved 0x400 bytes for rid 0x24 type 3 at 0xfebff800
atapci2: AHCI controller reset failure
device_attach: atapci2 attach returned 6
%%%

With 6.2-RC1, the only way I can boot this machine is to use the JMicron 
controller in my PCI-e slot.

The onboard controller simply will not work. There is no way of 
disabling AHCI support in the BIOS. Using a peripheral card isn't really 
an acceptable long-term workaround.

Perhaps we should consider adding a hint to ata(4) not to use AHCI for 
situations like this?

Has anyone else seen this problem?

BMS
