You need to apply patches in the following order: http://linux.junsun.net/patches/oss.sgi.com/experimental/040419.a-cpu-timer.patch http://linux.junsun.net/patches/oss.sgi.com/experimental/040420.a-cpu-timer-for-smp.patch http://linux.junsun.net/patches/oss.sgi.com/experimental/040426.a-hrtimers-2.6.5-1.0.patch http://linux.junsun.net/patches/oss.sgi.com/experimental/040426.b-mips-hrt-2.6.patch These patches are tested on NEC Rockhopper boards and Broadcom bcm1250 boards (in SMP mode) against linux-mips.org CVS tree around April 20, 2004 (kernel 2.6.5). If you want HRT working on other boards, you need a) make sure the board is uing cpu timer as system timer b) enable CONFIG_CPU_TIMER for the board Jun
