Hello
I have PC/104 board on AMD Geode chip (Kontron MOPSlcdLX) CS5536
Up to Linux kernel version 2.6.18 all worked fine.
But after 2.6.18 and up to 2.6.26 network and USB not worked.
After study kernel changes we discover what modul geode_aes lock all PCI
interrupts.
On board MOPSlcdLX BIOS assigned two PCI interrupts 11 and 12.
Network e100 driver and USB drivers assign 11 level.
VGA and Geode LX AES Security Block assign 12 level.
But if module geode_aes loaded then 11 level full locked and no one
interrupt here no comes.
Now we put geode_aes to blacklist and all work fine.
If your will need some information from working board send request please!
Regards, Roman
