Looks like KPB is out of memory. Can you reproduce with IPC4 and Zephyr config ?

@cujomalainey fyi - proof of concept seems to work.

May need locking too.

> he firmware does not accept any config before the probe dma is started Why not, would seem reasonable ?

@ranj063 pls take a look, and include this in the multicore branch.

This should also invoke the GDB stub at some point in RO and polling mode

IPC timeouts are P1. @juimonen are you able to get any mtrace out to help with this ?

@wszypelt can you check with https://github.com/thesofproject/sof/pull/4715

@lyakh fyi

@wszypelt are you able to check HEAD now with #4722 on top (one other fix is in head).
