Indeed, it appears to be so. I have a brand-new ASUS M3N78 Pro motherboard. After some Google searching it appears this mobo has a lot of flakiness and general instability under Linux. A lot of users mention random hard locks related to the NVidia driver and this board. Also mouse freezes, which I am currently experiencing. If I unplug and replug my USB mouse or keyboard, they won't reconnect. The BIOS is the flakiest thing I've ever seen in my life... several times it has just "forgotten" settings on a fresh boot (things I had disabled, like the fullscreen logo, suddenly come back), the ExpressGate works only when it feels like it, and sometimes I'll get a "CMOS checksum error, factory settings restored". A lot of the time, after a lock-up and hard reset cycle in Linux, the mobo refuses to even boot back up, I have to actually turn off the power supply for a couple seconds.
There are a lot of solutions mentioned online, various kernel parameters like "pci=nomsi", "noacpi" and "acpi=off" (none of these have worked for me so far) and even disabling the onboard USB completely as the source of some of the lockups seems to be a conflicting IRQ between the onboard GeForce 8300 and the USB controller. I will try manually installing the latest drivers from the NVidia website. If that doesn't work, unless anybody else has a suggestion I'm going to send this board back (for the second time) and try something completely different. I guess that'll teach me to do some Googling before buying new hardware :-( -- Resizing KDE4 panel locks up entire system https://bugs.launchpad.net/bugs/370207 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
