Raspberry Pi3 anyone loose eth0 with the last update?


I just rebooted both my 3's and lost eth0 on both, anyone else run into issues?

FWIW I lost wlan0 after one of the previous updates. It'll connect but won't associate (if that is the correct term) with my house wifi. I can ssh into it via wifi but nothing I have tried will get the wifi to (a)surf the net and (b)connect on boot.

I've googled the thing for hours and tried every config of inet1.conf and wpa_supplicant I could find, reverted to older firmware etc etc etc but I just am missing something. Bluetooth is a no-go also.

Right now it's on
Code:
uname -r                                               
4.4.11-v7-arm
and chugging along quite well so I'm nervous to run another update or upgrade.

Perhaps something went wonky on the Broadcom side of things?

Its strange. I rebuilt one with 14.2, did a slackpkg install slackware then the rpi-update and rebooted and all is fine.

Did the other and after the reboot it does a kernel panic. I'm pretty sure I did everything exactly the same but got two different results.

It doesn't have anything to do with DT overlays being disabled in /boot/config.txt does it?

Doesn't look like it, both are the same

Code:
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p3 rootfstype=ext4 kbd=us nic=auto:eth0:static:192.168.1.10:24
Well that is odd, just putting the microSD back in the Pi3 it booted fine.

I had that too, each update from rpi-update caused a kernel panic upon reboot. I worked around it by doing an fsck -trawl on the first partition of the card on a separate machine.

That's a nice /boot/cmdline.txt config. Here's mine:

Code:
dwc_otg.lpm_enable=0 console=tty1 nofont root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro
Sometimes Slackware ARM on my RPi3 crashes, which usually only happens while compiling. I haven't worked out yet what causes the problem but ejecting and re-inserting the microSD card usually solves it. This can happen after the same card has been working for days/weeks without a problem and, from experience, I've found this happens with the Samsung EVO microSD cards more so than other brands.

I do the same thing on the rare occasions when it crashes during boot-up and/or results in a kernel panic. There's no reason why taking the microSD card out and plugging it straight back in should fix the problem, but it seems to work every time.

I used rasbain's cmdline.txt and just removed what I didn't need and added a couple thing I did.

My working system gave an error on the sd card last night and rebooted to a kernel panic. Pulling the card out and putting it back in it did boot without a panic but the drive needed checked. After checking and fixing it reboots to a panic again.

I used to be able to run for months without a problem until I started running the rpi-update so maybe there is something related there.

Ok, so confirmed something with the kernel or drivers rpi-update installs. I rebuilt one and didn't do the update and its been fine.

It would surprise me to learn that rpi-update was the culprit. I have been advised by somebody more qualified and learned than me that it could be a timing (sync) problem between the system and sd card which causes problem such as these.

well so far without running rpi-update mine are stable. My guess is whatever problem got into the newer kernel or firmware rpi-update is installing.

Very strange, but certainly worth investigating. I'm going to do some testing on my problematic microSD cards too.
