On Fedora 20 using latest updates, it hangs after about four hours. I will be watching a Mythtv show and then it just stops. This is an i7-920 with the HD-PVR (USB).

I am using MythTv .27 along with MythWelcome.

I check journalctl and do not really see anything in there that might be causing a problem. I have MythWelcome outputting to a log and there's nothing in there about it having problems.

I checked SMART status on both drives and they are ok. They had been in a Fedora 12 without any problems.

I try a reboot and it seems like it takes forever (sometimes I give up after a few minutes and just press the power button to do a hard shutdown). I can see on the screen this time shows "OK Started Builds and install new kmods for akmod packages".

I had this hang problem pretty much since install of Fedora and Mythtv. I have done yum update a couple of times thinking something would be fixed, but it has not.

I have seen an dmesg that hangs on about 7 seconds during boot and google it, but have not tried the solution for it.

Any ideas on what else to look at?

My problems with Fedora often went back to the ramdisk. I would make my own and that would solve them.

Beyond that, there is som update-minimal command. Yum characterises updates as bugfixes, and "enhancements." The yum update-minimal command only gives you the bug fixes. I am not conscious of needing enhancements, and they seem to be more trouble than they are worth.

I'm also getting a lot Script reading problems from Firefox and Google-Chrome that keeps Locking up my computer, and Hard Drive is working Overtime.

I open a new user on my computer to see if I could away from old user settings, and no I still got the same problems in new user as I did old user.

I will probably get flamed for saying this, but I found Fedora installs had a useful life of about 2 years on average. Crazy problems would then start creeping in. I have managed to avert that with the minimal update strategy, but it's not ideal. The only reason I use Fedora now is for the Electronic spin, and I don't even do much with Electronics these days, so I have it safel;y locked away in a VM..
