f13 Posted August 3, 2010 Posted August 3, 2010 на других серверах clocksource тоже tsc? Вставить ник Quote
m_medved Posted August 3, 2010 Posted August 3, 2010 на другом сервере наверное Tickless kernel Вставить ник Quote
shaytan Posted August 3, 2010 Author Posted August 3, 2010 (edited) Tickless System - в ядре не включена на всех серверах. clocksource везде tsc. Единственное отличие в ядрах - это драйвер сетевой карты. Там где таймер грузит CPU0 используется igb. Edited August 3, 2010 by shaytan Вставить ник Quote

shaytan Posted August 4, 2010 Author Posted August 4, 2010 (edited) Похоже проблема в железе (PIC) На железе HP DL160G5 (Intel 5400 Chipset) проблемы нет, а стоит переставить систему на HP DL160G6 (Intel 5520 Chipset) так проблема появляется. Здесь описана аналогичная ситуация. Edited August 4, 2010 by shaytan Вставить ник Quote
