Bug#677472: More thoughts on OHCI USB ports and ACPI S3 State wakeup bug of ASUS mainboards
Hi,
Hmmm, more I think about it, this is a strange bug.
First of all, I do own more EHCI/OHCI USB-based mainboards in my apartment, but they are mainly MSI/AMD chipset (ATI Technologies origin).
Most MSI mainboards I own are fairly new ones, sold in the last 3 years.
I do own a number of fairly new mainboards because MSI tends to fire sale them with or without Mail-in Rebates at Fry's Electronics more than any other mainboard manufacturer I can think of (Some of them are demo models with occasional missing accessories.).
If you don't live in the U.S., Main-in Rebate is a "scheme" that the consumer has to cut out the UPC code from the box and mail in a copy of the receipt to some specified address, and I will receive the money back 3 months later.
Yes, it is legal, but people hate it, and the manufacturer "hopes" that only 50% or less people will fulfill the rebate requirements.
I have received 99+% of my Mail-in Rebates back, and every one of them have come back from MSI.
That story set aside, I have observed that ACPI S3 State resume works very well with recent MSI/AMD chipset mainboards.
I always thought that AMD chipset with PCI Express is fairly new, and that reason alone was why it worked so well with Linux.
The only AMD/ATI Technologies chipset I have had issues with is Radeon Xpress 200 (AMD and Intel flavor), and it looks like the integrated graphics part is causing the ACPI S3 State resume freeze.
Anyway I don't want to repeat myself, but I have the following ASUS mainboards I haven't really tested yet.
- ASUS A7N266-VM/AA (nForce) (http://support.asus.com/knowledge.aspx?SLanguage=en&p=1&m=A7N266-VM/AA)
- ASUS A7N8X-E Deluxe (nForce 2. If I recall it correctly. Some of the caps are bulging though.) (http://www.asus.com/Motherboards/AMD_Socket_A/A7N8XE_Deluxe)
- ASUS A8AE-LE (Radeon Xpress 200. Special HP OEM mainboard) (http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c00496280&lc=en)
- ASUS P5N32-E SLI (nForce 680i SLI) (http://www.asus.com/Motherboards/Intel_Socket_775/P5N32E_SLI/)
I also have one each of GIGABYTE and MSI nForce 2 chipset mainboards as well.
Other than that, most of the new stuff I have are from MSI (AMD, Intel, NVIDIA chipset).
I also have a few more ECS mainboards with SiS chipset, but many of their BIOS don't bother to implement ACPI S3 State (ECS L4S5A/DX+ mainboard is the rare exception.) even though the hardware supports it.
I will do the testing after I get back from my trip.
In the mean time, I have access to ASUS P5N-E SLI for testing purposes for 10 more days.
