I suppose the "IRQ handler mismatch" happened just because you enabled wrong rtc driver(s). It would be irrelevant. In general, softlock just after "Freeing unused kernel memory" can happen because /sbin/init crashed for some reason (kernel keep sending signals to /sbin/init). 1. Enable second and third "#if 0" blocks in arch/mips/mm/fault.c 2. Add printk() before each force_sig() in arch/mips/kernel/traps.c, branch.c, unaligned.c might show you what's going on. Also, SYSRQ-p or SYSRQ-t (BRK + p or BRK + t for serial console) might be helpful, but it seems UART driver of your target board does not support the MAGIC_SYSRQ feature... --- Atsushi Nemoto
