Package: src:linux
Followup-For: Bug #843308
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
using a usb bluetooth dongle and a usb headset for sound playback i had the following
messages in dmesg repeated at a rate of more than 1/second:
[99120.582909] AMD-Vi: Event logged [IO_PAGE_FAULT device=00:12.0 domain=0x0005 address=0x0000000000000080 flags=0x0020]
* What exactly did you do (or not do) that was effective (or
ineffective)?
- pulled the usb dongle but the dmesg messages kept spamming
- issued the "rmmod ohci_pci ; modprobe ohci_pci" command -
this seemed to reset the usb devices (the dongle was already pulled out)
and the spamming stopped
Did not have issues like these with the previous kernels.
My hardware is Gigabyte F2A88X-D3H mobo with AMD A8-6500 CPU
