OK, a little more info. It seems at least part of the issue is the Atheros wireless. With Wheezy installed, when I boot with kernel 3.2.0-4-amd64 I get a few dozen repeats of the following message:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
and I cannot connect to my router.
With lspci my wireless card is:
06:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01). I installed all firmwares with apt-get install firmware linux after adding non-free to my sources.list, although I think the Atheros firmware is free.
There is an existing Debian bug report on what seems to be the same issue:
Bug#727772: linux-image-3.11-trunk-amd64: Ath9k module stop working, DMA error
So maybe I have to go back to Squeeze for the time being as my computer on Wheezy isn't much use without networking. I'm still not certain this is the same problem I encounter during attempted install of Jessie as I never get out of the installer.
Thanks for any suggestions.
