Upon further testing, it appears that my USB devices work with mem=2G also- which is weird, because I would have expected odd things to happen after 0x40000000, not 0x80000000.
Are there any more diagnostics I can perform? I understand that fglrx taints the kernel, is there any way of booting without that module to test things? -- USB devices stop working with more than a 768MiB of memory https://bugs.launchpad.net/bugs/221719 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
