Here are two suggestions to try to narrow this down a bit:
- Try with just 1GB of 4GB enabled instead of 2GB to see if
that works reliably
Well, I tried but was not able to easily tweak U-Boot to use just 1GB. U-Boot did hang then.
Got my pyra 4G board set up last night here, and I noticed it would hang often while booting even with 2GB and no LPAE. I only saw any kind of oops once or twice, most of the time it just hung. Is this what you're seeing too?
What I could do was to use 2GB in first + 100M in second bank. This appears to show the same issues.
OK
- Revert commit 7abdb0e23e7b ("ARM: OMAP5: Add basic cpuidle
MPU CSWR support") to see if it's somehow PM related
Didn't show a noticeable effect either.
OK
Just a note: what I see since 4.13-rc1 is

Is this with just the 4G model? If there is a memory issue, the oopses can be random all over the place.
