Haa seems like you are right! With "ftrace=function
ftrace_filter=msm_read" , I can trigger the crash, but
sadly "ftrace_notrace=msm_read" also crashes.

So there's more than one problem area.

What about ftrace_notrace=m*

?

That too crashes.


So something else is causing an issue besides just msm_read.

Can you do an objdump -dr of the entire vmlinux binary and gzip it and
post it somewhere. Not sure if it would be too big to email. You could
try sending it to me privately. I'd like to see the binary that you are
using.


I have sent the objdump and dot config to you privately.

Thanks,
Sai
