The problem seems to disappear if the kernel option noapic is added. Now an other problem shows up instead. After a while the kernel says the following:

The mouse and keyboard start to work normally again if the ehci_hcd module is removed. I guess that the ochi_hcd module takes over all usb functionality in that case. I can modprobe ehci_hcd module again and the system works normal. -- kernel freeze on HP Pavilion dv9000 Turion64x2 https://bugs.launchpad.net/bugs/112775 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
