The latest kernel available for my distro, or the latest kernel available
"from Linus"? I've already tried the former.

For all I know (I'm not that knowledgeable on those things, mind you) this
happens completely at random. There hasn't been any pattern when the PC
would become unusable, and the OS unresponsive.

I'm not aware of any feature to change the buffer size in any of the
programs that cause the lock-ups.

That patch is for kernel sources or for the above snapshots I mentioned? Or
perhaps there are more recent ALSA source codes?
