@Maciej S Try killing the process udisks-daemon before suspending. It seems that actually accessing (polling/reading) the dvd drive after a suspend/resume triggers this bug. I don't need the dvd drive anyway, so I blacklisted it for now for udisks-daemon through udev rules (see Bug #379780 if you're interested) but of course it's definitely not a permanent solution.
PS: The IDE channels are driven by the driver pata_sis. we could really need the hardware documentation for this chip. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/467127 Title: ksoftirqd/0 hogs one core after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/467127/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
