Hi, The trivial patch below fixes the LDR and LDL instructions. Before modifying a register, it is better to load it :)
With this patch I am able to boot a 64-bit MIPS kernel on the emulated Malta board up to the start of INIT. Then I get: Freeing unused kernel memory: 168k freed modprobe: FATAL: Could not load /lib/modules/2.6.21.1/modules.dep: No such file or directory INIT: version 2.86 booting schedule_timeout: wrong timeout value 7ffffffffffffffe Call Trace: [<ffffffff80107700>] dump_stack+0x8/0x38 [<ffffffff803f9ce4>] schedule_timeout+0xdc/0x108 [<ffffffff80194828>] do_select+0x428/0x548 [<ffffffff801bbbfc>] compat_core_sys_select+0x1a4/0x230 [<ffffffff801bdb64>] compat_sys_select+0x104/0x1f0 [<ffffffff80115108>] handle_sys+0x108/0x124 This call trace is then printed in loop. Note that the kernel part of the 64-bit boot log is now the same as the 32-bit one, except for the addresses. The 64-bit specific error messages (for example the USB ones) are fixed with this patch.
