OK, nailed it.

It's commit 5f08e46b621a769e52a9545a23ab1d5fb2aec1d4 aka "atl1: disable broken 64-bit DMA".

With this commit in tree, I can reproduce either
a) kmalloc-2048 corruption after initscripts shutdown eth0
	http://marc.info/?l=linux-kernel&m=120820360221261&w=2

b) or oopses at filp_close() first reported long ago
	(sorry, can't find that email)

c) or hard hang after initscripts shutdown eth0 with even SysRq not working.
	http://marc.info/?l=linux-kernel&m=120795046008115&w=2

I have two boxes one with atl1, 4G RAM with 2G remapped after 4G boundary, another
with r8169 connected with just ethernet cable. NICs agree on 1Gbps speed.

So, it's enough to scp 200 MB git archive and immediately start
rebooting sequence for horrors described above to appear. It's not 100%
reproducible but more like 90%.

I tested 10 times kernel one commit before and it doesn't have these
issues and reboots reliably.

CONFIG_IOMMU is in use, dmesg, lspci, /proc/mtrr below:
