Re: dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

This system is more in use at the moment and over Christmas, so I'll probably not be able to mess around with this for a bit. What is worth noting is that this is the very first hardware version, as reported by "cat /proc/cpuinfo": processor : 0 model name : ARMv6-compatible processor rev ...

Re: dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

Okay, so the behaviour is different without the ethernet plugged in, and it didn't crash outright. Instead I got multiple kernel OOPSes. Unfortunately, as soon as I plugged a USB stick in to save the output from dmesg it locked up. Should have just saved to SD card, don't know what I was thinking. I...

Re: dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

Yeah, I'm just using it cos I had to use the aarch64 kernel for a particular use case on a Pi 3B+, and since heard the dwc2 driver is generally more reliable, if a bit slower. This seems to be reflected in a network of Pi Zeros I help administer and maintain that had weird intermittent issues a few ...

Re: dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

Okay, it crashed again, and I've done as you said and posted at: https://postimg.cc/3kzZymCF Unfortunately I think this time the top of the trace might be missing because the terminal scrolled. Hopefully nothing important is missing. It seems to be slightly different each time, so if you need more c...

Re: dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

Thanks for the help. I have removed the kgdbox option and added the slub_debug option as you suggested. I wonder if this might be an issue only with the original RPI - it's working fine on my RPI 3 B+ and several Pi Zeros. Regardless, worth trying to look into it. Is there any way for me to dump the...

Re: dtoverlay=dwc2 causing errors and kernel panic on Raspberry Pi 1 Model B (256 MB RAM)

I've decided to write the content of the screenshots up - makes it quite a lot easier to see what's going on. I have substituted the uptime for ** Number 1: [ **] 8<--- cut here --- [ **] Unable to handle kernel paging request at virtual address 31a60a02 [ **] [31a60a02] *pgd=00000000 [ **] Internal...

dtoverlay=dwc2 causing errors and kernel OOPS on Raspberry Pi 1 Model B (256 MB RAM)

Hi, I've been using the DWC2 USB driver on a Pi 3 B+ for a while, and a charity I volunteer at is also using this option for several Pi Zeros. I recently deployed an old Pi 1 Model B rev 1 (256 MB RAM) and have found that using DWC2 is causing lockups and errors in dmesg (see below screenshots). Bot...
