Following on from my /message/164266# 164266 other hang at 5A thread regarding this issue, I have stumbled across other combinations that also hang at 5A that do not involve a usb hdd or the DiNovo k/b - mouse dongle. In fact in these combinations, a usb hdd stops the hang.
I've been using a http://www.jaycar.com.au/productView.asp?ID=XC5146 Digitech xc5146 hard wired usb k/b, a http://www.logitech.com/en-my/support/mice/3295 logitech v220 wireless mouse with matching c-uay59 dongle and usb sd/mmc http://www.manufacturer.com/product/i44163-card+reader+-+AC-6000.html card reader model ac- 6000
All three must be plugged to particular rear i/o usb2 ports.
Removing any one of the items = no hang
Adding a usb hdd to another rear usb2 port = no hang
The arrangements that cause a hang are:
lan and 1394 are only included as reference to the port arrangement, nothing is connected to them.
'Hub' is the card reader
'Mouse' is the c-uay59 dongle
lan 1394 lan
hub - -
k/b mouse -
lan 1394 lan
k/b - -
hub mouse -
lan 1394 lan
k/b - -
mouse hub -
other arrangements that also hung were as per above but using the ports under the r/h lan port, e.g. as per below
lan 1394 lan
- - k/b
- hub mouse
or using the upper middle port e.g. as per below
lan 1394 lan
- hub k/b
- - mouse
Whilst I have not tested all possible combinations [I'd be there forever!!] it did seem that any other combination did not hang.
Hoping this might help Intel hunt down the culprit!
Intel - you should offer a bounty for information that leads to the arrest of a bug, then the whole world is your RnD lab!! [I'm serious!!]
edit: the dongle for the http://www.logitech.com/en-my/support/keyboards/192 DiNovo wireless keyboard/mouse is a http://logitech-en-ap.custhelp.com/app/answers/detail/a_id/9897/section/troubleshoot/crid/404/lt_pro... c-uv35
