i've got a lemote desktop with a quad core Loongson-3A in it: http://www.lemote.com/products/computer/fulong/348.html i'm trying to build my own kernel for it, but userspace just crashes on me :(. the current kernel is a precompiled one from lemote themselves, and things are compiling/running fine with it. but it's a bit stale and missing features i want (like namespaces & seccomp). $ uname -a Linux lemote 3.5.0-9.lemote #1465 SMP PREEMPT Mon Aug 26 14:23:38 CST 2013 mips64 ICT Loongson-3A V0.5 FPU V0.1 lemote-3a-itx-a1101 GNU/Linux the userland is Gentoo. it's an o32/n32/n64 multilib with n32 as the default. most (if not all) of userland has been built with gcc-4.8.2 using "-O2 -march=mips64 -mplt -pipe". $ file /bin/bash /bin/bash: ELF 32-bit LSB executable, MIPS, N32 MIPS64 version 1 (SYSV), dynamically linked, interpreter /lib32/ld.so.1, for GNU/Linux 2.6.16, stripped $ /lib/libc.so.6 GNU C Library (Gentoo 2.19-r1 p3) stable release version 2.19, by Roland McGrath et al.
