Hi Jian-Hong,
There's a Dell machine with RTL8106e stops to work after S3 since the commit introduced. So I am wondering if it's possible to revert the commit and use DMI/subsystem id based quirk table?
It's because of commit bc976233a872 ("genirq/msi, x86/vector: Prevent reservation mode for non maskable MSI") cleared the reservation mode, and I can see this after S3:
[ 94.872838] do_IRQ: 3.33 No irq handler for vector
If the device uses MSI-X instead of MSI, the issue doesn't happen because of reservation mode.
Hi Thomas,
Is it something should be handled by x86 BIOS? Because I don't see this issue when I use Suspend-to-Idle, which doesn't use BIOS to do suspend.
Kai-Heng
