 Posted: Mon Apr 24, 2006 4:12 pm Post subject: New kernel, sound locks up system (and what are mtimes?) |
 |
|
I upgraded my kernel from 2.6.15-gentoo-r6 to 2.6.16-gentoo-r3, but now everything that wants to make a sound locks up my system. I'm using the alsa-driver for my emu10k1 soundcard, I disabled the card in the kernel config.
Any idea how to solve this? Is it something I did wrong while upgrading?
When booting, I also get a few "Re-caching dependency info (mtimes differ)" messages, where there were none before. What are mtimes and is it bad that they differ? |

Here's what dmesg has to say after I tried to open a webpage that probably wanted to make a sound:

| Re-emerging baselayout should take care of the mtimes differ issue. I've also heard some people say that executing env-update has resolved the issue as well. |

the 'm' stands for modification - that's the time a file was last modified. Most likely the init scripts do some sort of sanity check based on them (but I'm not knowledgeable enough to tell you that bit  ) |

Bot machines on which I've just recently updated baselayout have many of those mtime message on bootup and shutdown. The one machine that I did not update has not such messages.
I'll try re-emerging baselayout.

There are threads on this... search for "mtimes."
I wound up removing the two files mentioned in another post, and re-running with the "--update" parameter, and the prob was gone for good. |
