[ATrpms-users] alsa-kmdl-2.6.20-1.2925.fc6

That happened to me too, and here's a patch to fix

-------------------------------------------------------------------

Rather than trying to patch the rtctimer.c in the rpm to fix the 
problem, I copied the rtctimer.c file to my /tmp dir, patched it, and 
after I started the rpm build, I copied the patched version of the file 
over the one that rpmbuild had just untarred.  Compiled fine that way.  
I had to package stuff in RPMs at an old job, and I hated it... don't 
want to deal with any of that stuff..   Hope it helps.  :)
