I cannot claim credit for the round-number observation; I'd just read the first few comments in the kernel.org bugzilla and noticed that one poster there mentioned he saw a different round number (200001).
The rest of the comments in the upstream bug indicate that this bug has been pretty much debugged to death: when the built-in bluetooth (which is connected to the low-speed USB controller) is enabled, the high-speed USB controller gets a steady stream of ~200 fake interrupts per second, and after a certain limit (100000 AFAIU) the kernel gives up and disables that IRQ. Why it happens nobody knows, and we probably need feedback from Lenovo engineers to figure it out. -- kernel disables irq after 10 minutes https://bugs.launchpad.net/bugs/126369 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
