The only way I can use my laptop is to boot with the last 2.X kernel from F14, which works fine. No matter what 3.X kernel I try, this happens. My laptop only has one internal HDD, and I never have a CD or flash drive mounted during boot if that helps. If there's a way for me to get some data about a failed boot, please let me know and I'll do what's needed.

I can't speak for anybody else, but having a card in the reader not only doesn't work around the problem, it causes more problems earlier in the boot process. And, I'll admit, the idea of having to keep a memory card in the slot just to get your computer to boot would Just Be Wrong.

Anybody, if I see these messages and am without ss_en=0, does this just result in log noise or does it cause ill behavior besides? I'm getting these messages, but on stateless deployments that boot from a SD card so I can't really test without a respin.

The log noise isn't "that harmless". It had caused /var/log/messages rsp. journals to grow beyond reasons and caused different kinds of hick-ups on slow, small RAM systems (I am suspecting it to be co-responsible for hard machine lock ups, I once was facing with journalctl).

I see the problem on my F18-based spins but not on the F20-based one nearing deployment. These two specific cases (18=bad/20=good) are both on Asus EeeBox B202 hardware, but there are many production variants of this "model" (grrrrr). Knowing you haven't seen on F20 is very helpful. > > Anybody, if I see these messages and am without ss_en=0, does this just > > result in log noise or does it cause ill behavior besides? > The log noise isn't "that harmless".

Hmmm... that worries me. My B202 deployments have been mostly good but more likely than other models to exhibit troublesome behavior. I should have systemd-journald conf'd where log growth isn't an issue, but ... I actually might be able to aid my F18-based deployments after all, despite what logic and reason would have my presume. I was able to rmmod usb_realtek, make the config you offered and modprobe it back in. I had been seeing the noise about every 50s and it's now been quiet for 5m. How I was able to make the change, I don't understand. The config file only hit tmpfs (because of the statelessness), but the tools I needed to do so once rmmod'd would have had to come off SD ... or from caching of the Live squashfs.img.
