[Bug 183461] Re: ksoftirqd/1 using 50% CPU or above
@david All the stuff i said before was kinda fumbling in the dark. The real problem is with the bcm43xx module, for your wireless card. Everything runs fine here, after i put the module in /etc/modprobe.d/blacklist. -- ksoftirqd/1 using 50% CPU or above https://bugs.launchpad.net/bugs/183461 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 183461] Re: ksoftirqd/1 using 50% CPU or above
About 2 minutes after removing the module, (the wifi card is turned off on my laptop), the laptop freezes, and the capslock light on the laptop blinks rapidly. Its not possible to send keystrokes to the kernel or anything, like ctrl+alt+prntscreen+REISUB. -- ksoftirqd/1 using 50% CPU or above https://bugs.launchpad.net/bugs/183461 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
[Bug 183461] ksoftirqd/1 using 50% CPU or above
Public bug reported: ksoftirqd (ksoftirqd/1) is using 50% CPU or above when idle. As others have already found out this is a bug with a module for a tv-tuner card. But I don't have such a card, and no such module is loaded.

Apparently, when I'm not using a dual screen setup, none of this happens...
