Adventures With Linux ™ Posted on January 20, 2020 by RGJanuary 20, 2020

As there is (so far) no sign of an update to the 5.4.x kernel series, I have uploaded a _very unofficial_ patch I had already created for 5.4.13, and I have tested this, and so far it seems to work OK..    It is based on an ‘earlier’ e1000e patch version found on linux/netdev.. https://www.spinics.net/lists/netdev/msg623693.html,  and thanks are … Continue reading →

Adventures With Linux ™ Posted on January 19, 2020 by RGJanuary 19, 2020

Kernel 5.5-rc7 is out, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/2001.2/04928.html This includes e1000e: Revert “e1000e: Make watchdog use delayed work”, and I have tested this, and it appears to have – finally – fixed the problem.

Ethernet – e1000e – The Saga Continues..

Adventures With Linux ™ Posted on January 13, 2020 by RGJanuary 13, 2020

After more testing, it appears that there is still a problem with the Intel e1000e driver and some – but not all – supported NICs.. I have several ex-HP systems that have Intel NICs, and some have more than one.   The HP Z820 has two (different models..): $ lspci |grep Eth 00:19.0 Ethernet controller: Intel Corporation 82579LM … Continue reading →

Kernel 5.5-rc1 has been released, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/1912.1/00242.html From limited tests so far, the Intel e1000e driver now seems to be working for all Intel NICs that use it, on my various systems.

Ethernet – Intel e1000e – Still Problems with Kernel 5.4.1, on Some Systems.

Adventures With Linux ™ Posted on November 29, 2019 by RGNovember 29, 2019

Tested the Intel e1000e driver in Kernel 5.4.1, and this still fails with some Ethernet NICs, but is OK on others.. On my HP Z820, there are two (different) Intel NICs, and the e1000e driver works with one, but fails with the other: LAN connection to eth0 (Intel 82579LM) fails: [ 125.292581] userif-2: sent link down event. … Continue reading →

Ethernet – Intel e1000e OK with some Kernel 5.4 Systems, but not all?

Adventures With Linux ™ Posted on November 24, 2019 by RGNovember 24, 2019

After updating my main HP Z820 system to Kernel 5.4, I found that the previous Intel e1000e Ethernet problem I had encountered on my test system with Kernel 5.4-rc6 seemed to have reappeared. (see http://rglinuxtech.com/?p=2632 ). But – this time, two of my systems with e1000e drivers were OK, but the third – the HP Z820 – … Continue reading →

Ethernet – Intel e1000e Still Broken with 5.4-rc6

Adventures With Linux ™ Posted on November 4, 2019 by RGNovember 4, 2019

Just tested Kernel 5.4-rc6 on a system with Intel e1000e, and this is still broken, despite being reported when -rc1 was released.. http://lkml.iu.edu/hypermail/linux/kernel/1910.3/07624.html Kernel release notes for 5.4-rc6 are here:   http://lkml.iu.edu/hypermail/linux/kernel/1911.0/01280.html The problem, is that the Ethernet connection repeatedly activates/deactivates, making the connection useless: (From KDE/Plasma)…………… Connection ‘eth0’ deactivated.

ARM64 – Odroid C2 – Tested with Linux Net-Next – Ethernet Still Hangs..

Adventures With Linux ™ Posted on December 18, 2016 by RGDecember 18, 2016

Recent versions of the Linux net-next tree could not be tested on the C2, as the meson-gx mmc driver was missing, but now it has been added, and I tested the latest version (December 17) – but the Ethernet hang is still there..      To be fair, this is probably because of the current patch conflict that has … Continue reading →

ARM64 – Odroid C2 – Ethernet Broken Again?

Adventures With Linux ™ Posted on December 12, 2016 by RGDecember 12, 2016

I had been trying to apply the latest round of Meson TX delay patches to the latest linux-next tree, but found that there seems to be a conflict with some of these..    The December 1 patched kernel now has some problems on my C2 with Ethernet traffic, so – for the time being – I have reverted … Continue reading →
