This will not be worked on atm (e.g. a bug closed for lack of user request, hardware etc)
This is a follow-up to #5120.
#5120 was describing a very regular DMA corruption type: every time the end of the ring buffer was reached when it was misaligned.
The frequency of
error: log_entry_address 0x____ is not in dictionary range
errors has massively gone down now (even before the alignment fix was merged). But it's still not completely zero, this sof-logger warning is still happening in some specific tests on some specific platforms. Note that unlike #5352 this warning is NOT fatal, most of the time the tests PASS with it. It now seems rare enough not make the sof-logger crash (it was taking #5120 very many corruption events to take down the sof-logger eventually) and it does not seem to happen at regular intervals anymore but it still happens.Looking for instance at daily run ID 10105, I found it happening more than 10 times in these tests (and a few others):

It's also happening in suspend/resume and pause/resume tests but I'm guessing it's more or less expected in those? So I ignored them. See thesofproject/linux/issues/3275 for more background.
After excluding all the "expected" cases, it seems to happen only on CML.
While #5120 was most frequent on Zephyr, the warning never appeared with Zephyr in 10105
