Hi! (i'm new here). I have managed to compile CVS kernels for 2.6.4 and 2.4.25 trees on my Raq2... And they work great. Now... Under heavy load (generating kernel_headers debian package), i saw the following: -cobalt:/proc# uptime Unknown HZ value! (79) Assume 100. 06:54:27 up 14 min, 2 users, load average: 1.77, 1.37, 0.69 cobalt:/proc# sar 2 2 Linux 2.6.4 (cobalt) 04/12/04 06:54:32 CPU %user %nice %system %idle 06:54:34 all 18.31 0.00 81.69 0.00 06:54:36 all 16.67 0.00 83.33 0.00 Average: all 17.60 0.00 82.40 0.00 cobalt:/proc# uname -a Linux cobalt 2.6.4 #2 Mon Apr 12 05:50:49 CEST 2004 mips unknown cobalt:/proc# What is : "Unknown HZ value!
