Comment 13 for bug 222174

I don't know why you are getting APIC errors. I certainly doubt that b43 is causing them - it seems much more like a BIOS error that b43 is triggering. These reports on ACER laptops are the only ones I have seen. Most users never see anything like this..

To save the output of a command, use the redirection operator ">", which creates a file. For example, use

lspci -nnv > output.txt

That creates the file "output.txt" and puts the generated output in it. If you use ">>" rather than ">", then the output is appended to the file.
