I compiled already two kernels on the new system ( pentium core duo E2000, 4 GB Ram, Biostar TF7150U-M7 Mainboard) but now I ran out of luck. The last view days I could not compile any kernel...

uname -a
Linux sombrero 2.6.27-gentoo-r7 #5 SMP Tue Jan 6 10:11:12 CET 2009 x86_64 Pentium(R) Dual-Core CPU E5200 @ 2.50GHz GenuineIntel GNU/Linux

gcc version 4.1.2 (Gentoo 4.1.2 p1.0.2)

Last message I've got is:

mm/built-in.o: In function `sys_mprotect':
(.text+0x14d22): undefined reference to `up_wride # !!!
make: *** [.tmp_vmlinux1] Error 1

"up_wride" is only in the object file. Can there be something like it anyway?
I am also not getting the same errors, if I just run make config, make mrproper,
(backup .config) make config with the same .config...?

I tested the ram with memtest 14 Passes - no errors....

Thanx for any sugestions!
