comment Horrible Iceweasel and Opera performance when watching youtube
Yeah, supposedly it's just firefox rebranded. I have a big quad core, but firefox 30.0 (fedora) plays youtube fine with < 5% CPU usage. On this page I get "The HTML5 player is currently used when possible" but only 2 of the 6 types are checked with firefox. With chrome 36.0, all six types are checked. IMO chrome is the most trouble free choice on linux and tends to do better on those kinds of "standards implementation" tests (e.g. acid3; actually in these versions both get 100% on that).

Have you tried chrome or firefox? I don' have any problems watching youtube with either of those.

You don't have to rebuild anything: httpd.apache.org/docs/current/custom-error.html This is why they have documentation ;)

comment Why doesn't rsync take advantage of the mv command when --remove-source-files is specified?
Fair enough (I'm not a downvote, BTW). I would take it as given that such a mechanism is available (e.g. statvfs(), POSIX), so your question implies to me you mean "since such a check is done anyway in this case", otherwise discussing -x is redundant; my point about -x is that's not "this case". But point taken. You still haven't said why you think it doesn't move the file -- I'm presuming you did some test, but there's no explanation of that in the question.

I don't know anything about RCU, but most likely cause (there's a long list at the end of that page) is probably a bug in some kernel code. You should check if there is really a correspondence between this and the "freeze" by examining other examples: is there always a stall during a freeze, and are there other stalls logged when no freeze occurs. I'd guess casually that the RCU stall is actually a very brief (< 1 minute) event..but it may have consequences in userland that tie the system up. In your example the stall seems to be toward the end of the freeze period (the timing is unclear)?

443 for SSH seems a dreadful choice to me. Presumably the networks which don't allow 22 out have a whitelist of ports, and that's why you can't use something more obsure (e.g. 567). If so and those networks present an external static IP, you could use a more obscure port and port-forward 443->567 for just those incoming IP's (blocking all others). WRT your "kernel panic", what's in that log isn't: kernel.org/doc/Documentation/RCU/stallwarn.txt
