You are right, "temporarily during boot" is not an accurate description. After further investigation, the message is not tied specifically to boot timing. I can reproduce it at any time by manually starting adsprpcd on QCS615 Talos: # adsprpcd which results in repeated: Error: dsp information is incorrect err: -1 The failure originates from the DSP capability query path, where the DSP side returns an error while handling the request. This feature is not currently available on Talos adsp. Therefore my intention is not to hide a boot synchronization problem, but to reduce console noise for a condition that appears to be platform-specific and non-fatal. I'll update the commit message to describe the issue more accurately in the next version.
