Description Jaak Ristioja 2006-01-09 23:38:54 UTC
The modules won't load. The snd module complains:

    [PATCH] move pm_register/etc. to CONFIG_PM_LEGACY, pm_legacy.h
    Since few people need the support anymore, this moves the legacy
    pm_xxx functions to CONFIG_PM_LEGACY, and include/linux/pm_legacy.h.

Indeed, i disabled CONFIG_PM_LEGACY, because i really didn't expect anything to depend on it. Anyway, i would have expected this:

 * Checking for suitable kernel configuration options:

To at least issue a warning. I hope this is relevant.

I have no experience with those checks, if kernel team can suggest something, it would really rocks :)
