sil3124 sata controller panics kernel

Tue Jul 29 17:07:18 UTC 2014

FreeBSD 8.2
AMD64

Has been running with jmb363 and sil3132 sata controllers for years.
siis(4) was last updated 2011-05-15.  The 363 died (reason unknown).
Bought 2 sil3124 cards Syba SY-PEX40008 PCIe-x1.  (the slots only
take x1 cards, and the 3124 has been recommended many times, I was
expecting it to "just work")

Boot to multiuser with 2 3124 cards and 1 3132 card (and 2 3726 PMs
connected to the 3132).  No drives connected to the 3124s.  System
running ok.  Hotplug a drive's sata data cable into a 3124 port.
(This works fine with 3132 with or without a PM.) 2-3 seconds later I
see a timeout message (common from siis(4)), and then the kernel panics.
Repeatable.  The 3124 is unusable.

I looked at the source code hoping to find a clue about the machine check trap,
but no joy.  What's going on?  How do I fix this?
