acer aspire 5050 gentoo kernel hangs on agpgart

namish · 02-28-2008, 02:05 PM

Hi, I just did a stage3 (kernel is 2.6.23-r9) install on my acer aspire. When I boot gentoo, it hangs on "Linux interface agpgart v0.101" I have my video aperture is set at 256MB, even though I'm sure that's not the problem; I don't even have X yet at this point. My video card is an ATI Radeon Xpress1100. Any suggestions?

Can you boot if kernel has no AGP support? Did you build agpgart for correct chipset (have no clue what's in Acer)?

agp support is required in the kernel configuration. my computer has an AT I Radeon Xpress 1100 chipset.

AGP is required only for 3D. It can be disabled if nothing else depends on it. ATI Radeon X1100 is your graphics card, not AGP chip. For instance, one of my computers has ATI graphics but VIA chip on motherboard.

Oh, sorry. I have an ATI RS480 chipset.

I'd say try BIOS upgrade first. And I'd disable agpgart to see if problem goes away. You didn't build any of those agp modules in submenu?

Ok, I did agp=off, and the kernel hangs on "Real Time Clock Driver v1.12ac." This is the entry right before the agpgart entry. Hanging on rtc is strange, since it is not included in my kernel config.

there are three hyphens next to the agp support in my kernel config, and when i view its entry, i get agp=y, so i don't think there is any way to compile my kernel without it.

So your BIOS is the latest? But when you installed you booted up with some other kernel and it worked. So try to find out what's different with your kernel. Otherwise, boot up with initcall_debug option and post for help in the kernel mailing list. They probably are interested in fixing this.

My BIOS is PhoenixBIOS v1.3309, which is pretty new, I believe. I'm not sure why that would be the problem. Phoenix also doesn't provide BIOS upgrades.

A couple of people have downgraded to 3303. Think this would be a good idea?

Edit: Crap... I'm an idiot. acpi=off boots it. Sorry for the waste of time.

If disabled ACPI boots it then it is a broken BIOS. Nowadays h/w manufacturers are in such rush to unveil new products that a fix a couple of months later is becoming a standard.
