Julian, The yenta_socket kernel module has a module parameter that is worth trying:
pwr_irqs_off=1 so can you reload the module with this to see if this helps. The module parameter has the oblique note stating: "Force IRQs off during power-on of slot. Use only when seeing IRQ storms!" which may help, but I am unsure if this is the once-on power on of the device, or if the device is powered on/off in many times over an extended period, hence you see the sporadic IRQ storms. -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 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
