I have the same here on an ASRock K10N78FullHD-hSLI mainboard (nvidia 8200 chipset) but furthermore sometimes my soundcard is just not responding.
I could make out the following: USB (OHCI-part) and VGA 8200 share the same IRQ 21 and USB(EHCI-part) and audio ALC1200 (onBoard) share IRQ 22 It seems to be an IRQ-sharing problem (probably with USB?) Taking the latest nvidia graphics drivers (180.51) make it happen less often, but it still happens. By the way i am using an AMD X3-(8650) Processor and 4 GB RAM - /dev/null ** Attachment added: "lspci_v.txt" http://launchpadlibrarian.net/26458680/lspci_v.txt -- usb ports randomly shut off Jaunty beta https://bugs.launchpad.net/bugs/350065 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
