Time for an update to this somewhat old thread. The problem has
remained, but being so very rare that I cannot reproduce it often
enough for systematic testing. Both motherboard and the "bad"
controller have been swapped out with different (but identical) cards.

These days there are some controller cards based on Marvell's 88SE9128,
which seems to be a decent chip. So the next step is chucking all the
sil3132 stuff in favour of those...
