This is not a pciehp issue, it's a networking issue:
In the stacktrace you've provided below, the rtnl_lock() is acquired
recursively, which leads to the deadlock:
unregister_netdev() acquires rtnl_lock(), indirectly invokes
netdev_trig_deactivate() upon unregistering some LED, thereby
calling unregister_netdevice_notifier(), which tries to
acquire rtnl_lock() again.
From a quick look at the source files involved, this doesn't look
like something new, though I note LED support for igc was added
only recently with ea578703b03d ("igc: Add support for LEDs on
i225/i226"), which went into v6.9-rc1.
The other hanging tasks are simply waiting for rtnl_lock() as well.

This is not a pciehp issue, it's a networking issue:
In the stacktrace you've provided below, the rtnl_lock() is acquired
recursively, which leads to the deadlock:
unregister_netdev() acquires rtnl_lock(), indirectly invokes
netdev_trig_deactivate() upon unregistering some LED, thereby
calling unregister_netdevice_notifier(), which tries to
acquire rtnl_lock() again.
From a quick look at the source files involved, this doesn't look
like something new, though I note LED support for igc was added
only recently with ea578703b03d ("igc: Add support for LEDs on
i225/i226"), which went into v6.9-rc1.
The other hanging tasks are simply waiting for rtnl_lock() as well.
