Applied on 2030, with small changes (I have removed *ALL* alloc_text)
from the code.
Thanks

Here is the patch, it just removes all paged code to make it
simple.
Thanks,
James

Hi James,
Please prepare a patch that removes all the #pragma alloc_text
from the code and we will apply it.
Thanks

Subject: Make all funcions no-pagable?
Hi,
We discussed this topic before. Today I saw system hangs
during shutdown again. This time function __restore_pci_config caused
the page out problem and stopped forever. Attached is the stack.
Is there any simple way to disable all the page pragma?
Or we have to go to each line the take them out?
#pragma alloc_text (PAGE, __restore_pci_config).
Thanks,
James
