Re: [E1000-devel] bug I219 - e1000e on VLAN network - Detected Hardware Unit Hang - kernel 5.15.44

2022-06-28 Thread Fujinaka, Todd 
I think this issue has been finally fixed recently after several attempts. The 
patches haven't hit the mainline kernel yet but should have been fixed in the 
intel-wired-lan kernel:
85988cbc0f22 ("e1000e: Enable GPT clock before sending message to CSME", 
2022-06-27)

There's a commit following that as well reverting one of the previous attempts 
to fix things:
46d6a94581e8 ("Revert "e1000e: Fix possible HW unit hang after an s0ix exit"", 
2022-06-27)

The intel-wired-lan kernel can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue.git/

Subject: [E1000-devel] bug I219 - e1000e on VLAN network - Detected Hardware 
Unit Hang - kernel 5.15.44

Hello,
i try 3 pieces of Gigabyte Technology Co., Ltd. H410M H V3/H410M H V3, BIOS FC 
03/25/2022 with integrated intel ethernet card I219_V14

The problem is, that card is working only few second, than stop for few second 
and repeating infinitely.
It happen on busy network with vlan. Syslog at bottom

Problem detected on vanilla kernel 5.15.44. I could test newer kernel, but 
there is no e1000e changes yet.

Hardware:
00:1f.6 Ethernet controller: Intel Corporation Device 15fa (rev 11)
     Subsystem: Gigabyte Technology Co., Ltd Device e000
     Flags: bus master, fast devsel, latency 0, IRQ 123
     Memory at 5130 (32-bit, non-prefetchable) [size=128K]
     Capabilities: [c8] Power Management version 3
     Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
     Kernel driver in use: e1000e
     Kernel modules: e1000e


User solution to avoid this problem is disabling tx and rx checksumming on card.
#ethtool -K eth0 tx off rx off

But the problem is in the driver (e1000e) for this network card. For another 
intel card this driver works fine. Another network module  works fine too.
Is it possible, at first, make something to disable checksumming when module is 
loaded for this I219_V14?

I try download and compile latest e1000e version 3.8.7 against kernel
5.15.44 but its incompatible.
