This causes significant system slowdown. The errors are the same as reported by commit 77a6407c6ab2 ("wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 11ad:1723") Add the RTL8723BE with subsystem ID 17aa:b736 to the rtl_aspm_quirks table to stop the AER errors. AER errors can still be present prior to pci probe, as the device by default may have ASPM enabled. Testing on a Razer Blade 14 2017 which shipped from the OEM equipped with an RTL8723BE card with this subsystem ID confirms that this patch resolves the AER flood and allows the wireless card to function normally once the driver takes over.
