Sorry about the delay, but I have gathered a bunch of information about the machine. For the record, I tried to put some order on the subdirectory at: http://www.ime.usp.br/~rbrito/linux/clevo/ On Sat, Jan 14, 2012 at 19:05, Yinghai Lu <yinghai@...nel.org> wrote: > On Fri, Jan 13, 2012 at 11:09 PM, Rogério Brito <rbrito@....usp.br> wrote: >> A warning, though is that there were some options regarding PCI buses >> which I did not know exactly how to answer.

Regarding these options, Yinghai, the options which I enabled once I typed "make oldconfig" were: CONFIG_PCI_PRI CONFIG_PCI_PASID > Please enable CONFIG_BOOT_PRINTK_DELAY in your .config > > and boot with "boot_delay=1000" or even "boot_delay=5000" > > then video capture could help. I did just that and uploaded a video from Linus's git tree with the options above to: http://youtu.be/_dYhkWHfep0 It took a long time to boot (about 7 minutes), but all details are there, I hope. I can repeat the same steps for your for-pci2 branch, if you want me to.

After searching, and searching, and searching, I could find this thread (in Portuguese) of some people with this computer, all of them having problems with multiple distributions (which is not a surprise, as the kernel has problems with these machines): http://www.forumdebian.com.br/topico-notebook-amazon-pc-amz-a-101-resolvido Just for the record, this Clevo was rebranded by a company called Amazon PC (the model is A101).

I took pictures of the few setup screens, and I reset everything to factory defaults, but still no luck. You can see the photos at: http://www.ime.usp.br/~rbrito/linux/clevo/photos/ > 2) Can you use a Windows tool like AIDA64 (free trial version at > http://www.aida64.com/downloads) to collect information about how > Windows configures the box? Sure, I downloaded it an generated some reports. Two of them with this tool that you mentioned and one with lshw. They are at: http://www.ime.usp.br/~rbrito/linux/clevo/hardware-description/ --- Comment #16 from Zhang Rui <rui.zhang@...el.com> 2012-01-18 05:39:52 --- hmm, what's the status of this bug? does the problem still exist in the latest upstream kernel? Yes, Zhang. Both bugs: https://bugzilla.kernel.org/show_bug.cgi?id=41622 https://bugzilla.kernel.org/show_bug.cgi?id=41722 are still reproducible with the latest kernels. Please, don't close them. OK. I'm going to bed right now, but I will be happy to provide any further information or test any patches/trees.
