Haven prime in the background taking 100% doesn't noticeable affect deskop performance. But I think I know where the problem lies: current: c0499a60 current->thread_info: c0528000 Initializing CPU#0 PID hash table entries: 4096 (order 12: 32768 bytes) Detected 2004.698 MHz processor. Using tsc for high-res timesource In above dmesg you can see that nothing was used as timesource, but here in current dmesg tsc is used. Is this normal or a bug? Need I pass a kernel paramtere when pm timer is enbaled? bye Prakash - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
