While I have absolutely 0 idea why and how, running
clear_bam_transaction
when READID is issued makes the DMA totally clog up and refuse to
function
at all on mdm9607. In fact, it is so bad that all the data gets
garbled
and after a short while in the nand probe flow, the CPU decides that
sepuku is the only option.
Removing _READID from the if condition makes it work like a
charm, I can
read data and mount partitions without a problem.

This is totally just an observation which took me an inhumane
amount of
debug prints to find.. perhaps there's a better reason behind
this, but
I can't seem to find any answers.. Therefore, this is a BIG RFC!
I'm adding two people from codeaurora who worked a lot on this
driver.
Hopefully they will have an idea :)
Sadre, I've spent a significant amount of time reviewing your patches,
now it's your turn to not take a month to answer to your peers
proposals.
Please help reviewing this patch.
Sorry. I was hoping that Qcom folks would chime in as I don't have
any idea
about the mdm9607 platform. It could be that the mail server
migration from
codeaurora to quicinc put a barrier here.
Let me ping them internally.
Oh, ok, I didn't know. Thanks!
Sorry Miquel, somehow we did not get this email in our inbox.
Thanks to Mani for pinging us, we will test this up today and get
back.
While we could not reproduce this issue on our ipq boards (do not
have a mdm9607 right now) and
issue does not look any obvious.
can you please give the debug logs that you did for the above
stage by stage ?
Regards,
Sricharan
