I remember there was a patch to fix some resource leak issue and later we agreed it was a false alarm (no bug in PciBus drver).
I am not sure if this is the patch we discussed earlier.
Hi, Hsueh:
It seems pcie device's hot plug operation is rare during UEFI BIOS phase.
Does this patch aim to solve usb4 storage hot-plug during UEFI BIOS phase?
