Hi List, I'm working on a 4Kec SoC. I'm trying to port a recent kernel (2.6.26-rcX from trunk) to my SoC but I have problem on timers (i think). The start sequence (start_kernel @init/main.c) freezes on the page_writeback_init() call. The page_writeback_init function calls the lock_timer_base function (by means the mod_timer/__mod_timer) that fails always the test likely(base!=NULL) (source file kernel/timer.c). The base variable (ponter to tvec_base) is always NULL, resulting an infinite loop. I'm using the cevt-r4t and csrc-4k standard mips 4k timer (on irq #7). With debugger I verified that the c0_compare_interrupt service routine is correctly invoked. Kindly, can anyone help me to understand what I need to check to solve this issue? If you need other information, please, ask me (This is my first mips port). Thanks in advance. best regards. luigi -- Luigi Mantellini R&D - Software Industrie Dial Face S.p.A.
