Hi, Just installed F9 preview and updated to latest. Rebooted everything was fine. Today, I booted the system again, played with it for a few hours, then I rebooted to test the "i915.modeset" (which is hyper cool thanks:) Now when the machine came up, I got: Primary superblock features different from backup: Check forced This was on the root filesystem. It checked the FS, and finally said "** Rebooting Linux **", at this stage I was fairly scared .. it looked like a serious problem! However, Fedora rebooted and it came up just fine! Well, I have no idea what just happened PS: Why did F9 disable Synaptics touchpad tapping!! This is going to make a lot of Laptop owners angry! At least it made me. Considering Windows and older Fedoras had it enabled, everyone is going to be not too happy about the change I guess. Anyway, if there's infinite wisdom about this, could we at least get release note tips on how to enable it back ? Thanks for the awesome work .. wifi works out of the box, Alsa too, correct wide screen, kernel mode setting ... etc Fedora is getting too good :)
