SATA: AHCI controller reset failure - After Upgrade

[Rômulo Lima]

Hi, 

Good morning, my name is Rômulo Lima, I had a problem when make an upgrade in my Freebsd Server from version 6.1 to 6.2. Before upgrade my SATA disc controller was working normally:

atapci1: <AcerLabs M5287 SATA150 controller> port 0xec00-0xec0f,0xe480-0xe487,0xe400-0xe40f,0xe080-0xe087,0xe000-0xe01f mem 0xdffff800-0xdffffbff irq 21 at device 31.1 on pci0
ad4: 78167MB <Maxtor 6Y080M0 YAR51HW0> at ata2-master SATA150

 But after upgrade I got the following error, and my SATA disc stops, after that I proceeded with a downgrade and may Server work fine again. 

atapci1: AHCI controller reset failure
device_attach: atapci1 attach returned 6

I search a solution on some mail lists, but I still have no solution to this problem, if anyone can help me I will thank very much!

Best Regards,
