Binary package hint: plymouth
Linux lucidity 2.6.32-28-generic #55-Ubuntu SMP Mon Jan 10 23:42:43 UTC
2011 x86_64 GNU/Linux
plymouth:
Installed: 0.8.2-2ubuntu2.2
I have a virtual machine running Lucid Lynx (10.04 LTS). In order to
access X remotely I installed XDM and made it listen to XDMCP requests.
However now after every reboot plymouthd process continues running
eating ~30% of my CPU (4 cpus are passed to the kvm instance). This
causes increased CPU usage by the virtual instance while not doing
anything useful. When I connect to the virtual console through virt-
manager/vnc it looks like plymouth has stuck and does not want to
release the terminal to XDM. The virtual machine uses standard qemu
cirrus video board with 9Mb of video RAM.
stracing the instance shows the following repetitive pattern:
