 Hello,
Just a silly question. Is there any working 64-bit kernel configuration for my r4k 100MHz Indy? From time to time i compile another new kernel for 64-bit... and see the thing dying. Recently it looked pretty well like Indy r4k 100MHz (BROTHER!?!?!) crash shown in http://www.linux-mips.org/archives/linux-mips/2007-11/msg00186.html
Everything but the kernel is debian stable: binutils 2.17
gcc 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)...

I would be very happy to give you any more info/do any test, if you are interested.

These are taken on 32-bit (usually working) 2.6.23.14 from linux-mips.org.
