Do you by any chance have pulseaudio installed? I ask because my sid
workstation started doing almost exactly this a few days ago. Also, some
applications worked, some froze. Iceweasel quickly ground to a halt,
Konqueror didn't. 'Almost' exactly, because initially it happened
sometimes. When it moved to happening on every boot, I had to fix it.
If I left it showing the console logon screen (after my DE had closed)
then after about half a minute it would display loads of trace
information, scrolling off the screen, and the only thing I could see
that I understood was 'alsactl'. I looked back at recent upgrades, of
course, but this is sid and there were perhaps a hundred packages
upgraded in the previous couple of days.
Eventually a few more clues confirmed that it was an audio problem, and
suggested pulseaudio, which I had installed a couple of months earlier
for a particular experiment. I ripped it out, and sound no longer
worked of course, but my computer would shut down again, and Iceweasel
worked. Running the alsa configuration restored sound.
