System has a constant load of ~1.00 with no intensive processes running. This has been a consistent issue on this machine since the F15 alpha. Currently running kernel version 2.6.38.5-22.fc15.x86_64. top shows no process using much CPU, nor any notable I/O wait. This is immediate after boot and load never goes down. Tried checking if this was perhaps some process running on and off fast enough that it wasn't visible in top. Running ps repeatedly didn't reveal any process, and the pids of the ps processes incremented in sequence demonstrating there were no other processes starting and stopping between ps runs. Hardware is a Lenovo Thinkpad with an Intel i7 CPU.
Did a fresh install of F15 and latest updates-testing packages on the same hardware and after the first reboot this problem persists. 2.6.38.5-24.fc15.x86_64
Idle load issue persists with latest 2.6.38.6-26.rc1.fc15.x86_64 kernel, even when booted into single user mode.
perf top shows 'drm_addmap_core' hovering around 20-30% of samples. Is that meaningful?
It's probably just a process stuck in uninterruptible sleep. The ps command should be able to show that. If it's not causing CPU load then it's not really harmful though.
