Kernel 4.14 problems

[mypiandrew]

Hi

We're running a CM3 on a custom carrier board we've had for a few years now.

Has been running quite happily up to 4.9.75, no problems. All Solid.

I've just done a rpi-update running on Jessie to test out the new 4.14 kernel and the system hangs on next boot up :

These look more interesting from a "going bang" perspective :

Adding these to the cmdline.txt file doesn't help

dwc_otg.lpm_enable=0 dwc_otg.speed=1

I did have other issues with the system way back on 4.4 with #1633 but I doesn't look the same to me as it's not even getting as far as systemd by the looks of it here

What can I do to assist with debugging this?

Full contents of config.txt please, and details of all peripherals connected to the device.
Booting off EMMC?
What's in /etc/fstab too? You appear to have an SD card exporting /dev/sda, so is that being mounted correctly?

/etc/modules too for any extra modules you're loading.

[mypiandrew]

Yes it's a CM3

I was just taking a cut and paste of the config.txt line and noticed and old overlay

I had this line still in ( I can't remember why off hand, wasn't there an issue with this at one point?)
dtoverlay=mmc

Removed it, and it's booting nicely now

Would that have caused other issues?

Without details of your custom system, it could be anything.

Hmm.. on removing the forced usb slowdown mods to cmdline.txt I am still getting a USB error that sounds awfully like what I saw before

Let me gather some info for you

This shows the system with a boot that has the mysterious error 71 on it

OK scratch the -71 error, I think there must have been a intermittent contact on the mPCIe card I was using to test. Given the edge contacts a clean and screwed the card in fully and it's booting AOK for the last 10 tries in a row.

Nice work, and thanks for the hand holding.
