Description rafal200725 2024-04-22 18:39:38 UTC 
When I connect ethernet to my laptop after it booted, one core of cpu reach 100%, and system start being unusable, command stop working.

On kernel 5.15 LTS, theres no issue, only on highest.

Bug appear for me in 6.8.7 stable and 6.6.28 LTS. (but may also on anothers, that only I tested). It may be ralated to new commits from about 2 weeks ago, that changes something in this driver.

Output from "lspci -k | grep -iA3 Ethernet":
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4) I219-LM (rev 21)
	Subsystem: Lenovo Device 225d
	Kernel driver in use: e1000e
	Kernel modules: e1000e

In advance sorry for my English I'm still learning this language.

If you need more info, just tell. I'm newbie so you need to guide me, to get some logs etc.
