The problem that Roger was talking about is a _host_ kernel hang (more
precisely, all processes of interest end up in D). This bug has been seen
in many kernels from 2.4.19 through 2.4.20-rc1 (and the -rc2 changelog makes
no mention of relevant fixes).
Interestingly, a recent post (yesterday) from Con Kolivas on lkml mentioned a
relevant-sounding patch he got from Andrea. If anyone has any ideas what
patch this is, I'd love to know.
I looked at Andrea's recent lkml posts and saw nothing that looked relevant.
