[ 4.372392] bf0ab3c0: Warn: trap[645]: Trapped: Thread: 2, reason: 00001000, PC: 400501A8, previous PC: 40050154
This is the exact core dump I've been getting as well. No clue how to tackle this one. Spoken with @Ansuel about it too. Very hard to decipher NSS FW errors as they're pretty cryptic in how the errors are worded and the little to no documentation.
I had suspected something to do with the memory reservation. Had the same error over 2 years with a discussion I had with @Gram (under Coredump 1). Disabling pstore/ramoops in this instance didn't help.
List of all the crashes trying different techniques to load it.
