Hi I am also facing the same problem with a whole batch of IBM ThinkCentre machines at my place of work. See comments inline.

All entries are 0.0! In the machines at my site, I observe that %CPU column oscillates between 0.0 and -0.0 (yes, that is a minus sign before a zero point zero). Very weird indeed. I had been looking for a solution to this problem since the past few days. All machines were running the Debian packaged kernel-image-2.6.7-* that was running just fine. This anomaly manifested itself only after an upgrade to 2.6.8-* and 2.6.10-* a few days back. I found the following bug filed against a 2.6.8 Debian kernel and it talks about the same symptoms as we have seen with the IBM machines. http://bugs.debian.org/284477 The solution (workaround) suggested there is to disable ACPI_SLEEP in the kernel. I am going to try this today and let us see if our problems disappear. For the moment I have booted with kernel parameter acpi=off. I'll report my observations here tomorrow. Please try this at your end and report back. -- Vipul Mathur vipul[at]linux-delhi.org http://www.vipulmathur.org/ ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
