I get invalid opcode: 0000 [#1] PREEMPT SMP error, with long backtrace, ending with Fixing recursive fault but reboot is needed! since log is quite long, I haven't attached it but it's available here: http://nik.lbox.cz/download/kernel.log Is this some known issue? Any chance upgrading to 1.7.1 will fix it? The system is centos6 with latest updates, qemu and kernel packages are self compiled. CPU is Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz If I should provide more debug info, please let me know. thanks a lot in advance! nik --=20 ------------------------------------- Ing.
