with tobiasbora solution i also get 100% cpu on ksoftirqd I am not sure if it helps but trying acpi=off the module does not load and I get a multitude of the messages
===>rt2x00lib_start genirq: Flags mismatch irq 0. 00000080 (0000:03:00.0) vs. 00015a00 (timer) phy0 -> rt2x00lib_start: Error - IRQ 0 allocation failed (error -16). As an aside, would it help if more people contact mediatek? I sent a question on their webform but haven't received a reply. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220146 Title: Ralink Mediatek 14c3:7630 wi-fi card isn't supported out of the box To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1220146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
