[solved] laptop sometimes hangs on startup

aligator · 2014-08-18 06:31:58

hi

my laptop sometimes (it is very random) hangs after/while the fsck. I only have something like this as output:

arch: clean, 126671/4055040 files, 1328288/16196864 blocks

after this it hangs, and the cursor doesn't flash anymore.

Moving from System Administration to Applications & Desktop Environments.

I suspect you have the 'quiet' parameter on your kernel line. As a zeroth step, please remove that for diagnostic purposes. Then as an actual first step, follow this wiki page to gather information that will allow us to help.

Very strange: since I removed the quiet parameter, it never hung again. and I restarted it twenty times...

That's most likely a coincidence. How often was it hanging with that parameter?

There is only one feasible (yet still very highly unlikely) way that adding 'quiet' could lead to such problems AFAIK. It is in principle possible that there is a race condition in startup events, and the lack of the quiet parameter slows down boot just enough to avoid that race condition. But again, while conceptually possible, it's well beyond far-fetched.

If hangs really were more frequent with 'quiet', did you also update anything in the intervening time? Does adding 'quiet' back make the hangs return?

I think every fourth time, but it was very unregular.

I added quiet back and restarted four times, and it again hung onece.
I update a few little things, but I don't think these were relevant on this.

and I installed a new arch (dualboot) and it has the same strange behaviour.

Hmm - then as skeptical as I was in presenting the idea, a race condition *may* be invovled. But only under the Doyle advice of "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." It's quite possible too that there is yet something else I didn't know was possible.

I think I let the quiet removed and everything is ok

Thank you for your help.

I have the same problem on my DELL XPS 15 since an update a few weeks ago. It was hanging on every boot until I removed quiet. Then for a while it worked, but since a week ago it hangs almost every time I boot. The thing is, when I shut down and boot again it never hangs again until it's been off for a while.
