Bugzilla Bug 184593

Pending the planned ~ masking of GCC-4.2 this week (gentoo-dev thread) i
thought I'd get an early start. 

I got this little sucker during my emerge -eND system    ( hey, 244 out of 433
packages ain't bad ;) )

I know I've seen this error before somewhere, but I'm buggered If i can find it
here on b.g.o 

Just so you know, I cant use any of the more recent drivers, im one of those
poor bastards with a GF4 ti4200 which Nvidia have told they don't love any
more.


Reproducible: Always

Steps to Reproduce:
I dont think you can get more repeatable than 'happens during emerge -eND
system'

Unrelated to gcc/glibc; disable CONFIG_PARAVIRT in your kernel.

Ah, knew it looked familiar. 

I thought I had already turned that off -last- time i had this problem. 

However, problem solved. Thanks again Jakub.

Well, the ebuild should check for this at least, until there's a better fix.
Reopening.

please re-test with 9639

See above and get back to us, please.

latest one is broken (100.14.19) and lacks a test/notice

i just made paravirt_opts EXPORT_SYMBOL() in my kernel to workaround it ;)

now we die on it.
