The udev .rules file causing the problem is: /etc/udev/rules.d/90-modprobe.rules
Specifically, this rule: [code]# Load drivers that match kernel-supplied alias #ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe -Q $env{MODALIAS}"[/code] In disabling this rule, I noticed an immediate effect - my onboard sound is not loaded. There may be other effects that I'm not aware of yet, but we'll see. I'm not familiar with the backend of Linux, but perhaps the "kernel-supplied aliases" need to be updated to support the ATI Radeon 9250? -- Cannot boot when video adapter set as PCI in BIOS https://bugs.launchpad.net/bugs/128421 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
