Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
> 6e98b09da931a00bf4e0477d0fa52748bf28fcce
> OS slackware64-current fully upto date, on an AMD 990fx motherboard with a
> Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 09).
> Linux-rt-devel-rc2-rt1 and linux-rt-devel-6.4-rc3-rt2 had same issue, previous linux-rt-devel-6.3.3-rt15 worked with no issue.

> Hello I suspect this series of commits is causing the full system lock im having when using the r8169 driver with linux-rt-devel-6.4-rc3-rt2. With the driver enabled my system locks up with a few mins of booting and logging into desktop. I have to use power off button and reboot to older kernel. With the r8169 driver blacklisted the kernel works perfectly.
> My syslog attachment shows the driver errors and after looking at commits I saw the above numbered as being the most likly cause.

See Bugzilla for the full thread and attached syslog.
Anyway, I'm adding it to regzbot:
#regzbot introduced: 6e98b09da931a0 https://bugzilla.kernel.org/show_bug.cgi?id=217519
#regzbot title: Networking pull for v6.4 causes full system lockup on RTL8111/8168/8411
Thanks.

Closing as there is already a confirmed fix (see Bugzilla):
#regzbot resolved: d6c36cbc5e533f
