Kernel26 upgrade -> cannot adjust bar0

dw · 2007-03-25 20:07:31

Hi.

I just updated arch to the last stock kernel and tried to reboot. Booting stops with one of the following error-messages:

0000:00:0d:0: cannot adjust BAR0 (not I/O)

assume root bridge [\_SB_.PCI0] bus is 0

I've tried booting the failsafe kernel too (as well as playing around with options such as acpi=off, noapic, nolapic,..).

Firing up google I found this which is pretty much what I'm experiencing as well. I have similar hardware too (pavilion dv9043ea) and I think as well that the problem is the device nVidia Corporation MCP51.

Question: Is it possible to boot a live-cd and revert to the old (working) kernel? What else could I do?

Update: I was able to boot with the pci=routeirq kernel-parameter. Don't know yet though, if this option works reliable all the time...

Update 2:
pci=routeirq doesn't work reliable. I've just tried about 15 times to boot but never got further than the "cannot adjust BAR0" error-message.

Anyone?

I just wanted to add that I had to downgrade to 2.6.20.3 which works fine.

Hmmm. Seems others have had some problems too. http://www.gossamer-threads.com/lists/l … nel/748576

I'm looking in here because I just experienced my first hard lockup in Arch.

I'm using the 2.6.20.4 kernel. Mayhap this one's a lemon.

No computers with the MCP51 chipset are able to boot this kernel at all. And this buggy kernel is the only one included with the new 0.8 release.

Well done, Arch!

well we only know if you tell us, unfortunatly, developers arent receiving telepathy training until 1.0. So in the mean time, report the bugs at bugs.archlinux.org, so we can squash them -- otherwise they breed.

Has anyone with an mcp51 chipset tried 2.6.20.5 or 2.6.20.6 already? Is any of these newer kernels working?

dw · 2007-04-08 09:46:33

Ok, just tried it out by myself. Doesn't work at all. I had to revert back again to 2.6.20.3, which works well....

Sorry... I'm just annoyed that I'm unable to use the latest version of my favourite distro.

I'll make a bugreport ASAP.

You could try and compile the newest kernel according to those information:
http://www.uwsg.iu.edu/hypermail/linux/ … /0250.html

Apparently it works if the mentioned patch is reverted.

Hope it helps.

Well, when you first have Arch installed, it wouldn't be any problem to revert to an old kernel or to compile a new one.
But no one with the MCP51 chipset (which is most modern HP and Compaq laptops) are able to install Arch Linux at all because of this.

ftp://ftp.archlinux.org/other/0.8/i686
use those they have an older kernel

I have MCP51 and I boot it every day since installing on new HDD from 0.8 beta.
The question - what do I do wrong?
Maybe stop complaining about buggy kernels and talking for everyone?

I'll look at your bugreport.

What happened with this bug? It just dissapeared from the bug reports and the bug is still there on the 2.6.20.7-2 kernel, I tried it last night and the error messages are still there. Is there anything I missed?

tpowa · 2007-04-22 16:27:15

bug was stated as fixed with latest kernels

AngelToledo · 2007-04-22 19:06:29

So, if Im still having problems with latest kernels, should I keep my 2.6.20.3-3 kernel?
