WiFi no longer works on Pinebook Pro after upgrade to kernel 6.18. It appears firmware fails to load:

With this commit reverted on top of 6.18.1 wireless connection works fine.

Not sure what could be relevant but:
- it's an early model, I think second batch, delivered end of 2019
- mainline uboot 2025.10 is used

Yup, IIRC the host_wake pin behaviour - at least the polarity, and possibly whether it's used as an out-of-band interrupt at all - is really a property of the firmware rather than the hardware, and can be different for different blobs.

Peter, Heiko, what's the deal here? This looks stalled. Is temporarily reverting an option, or would that cause regressions for other users that already benefit from the change that is causing the problem?

Peter, Heiko, what's the deal here? This looks stalled. Is temporarily reverting an option, or would that cause regressions for other users that already benefit from the change that is causing the problem?

I assume this wasn't fixed yet (Jan, please correct me if I'm wrong!):

Heiko, could you maybe submit a revert? Fixing this is long overdue afaics, as Linus just recently wrote ""rule of thumb [to get user-reported regressions fixed] should generally be "within a week", preferably before the next rc.""[1] – we are way past that.

Note, I assume this will break things for people where the change in question improved things. But I suspect he in a situation like this Linus prefers to go back to what was "normal" before the culprit was merged. If we are unsure about this I guess we should get him involved to clean this up.

Ciao, Thorsten

With this commit reverted on top of 6.18.1 wireless connection works fine.

Not sure what could be relevant but:
- it's an early model, I think second batch, delivered end of 2019

Is it the Synoptics or the Cypress/Infineon module? What firmware are you using?

Quoted 4 lines

- mainline uboot 2025.10 is used

Peter, Heiko, what's the deal here? This looks stalled. Is temporarily reverting an option, or would that cause regressions for other users that already benefit from the change that is causing the problem?

I assume this wasn't fixed yet (Jan, please correct me if I'm wrong!):

Just to make it clear in case anyone is waiting for confirmation: the issue is still present.

Heiko, could you maybe submit a revert? Fixing this is long overdue afaics, as Linus just recently wrote ""rule of thumb [to get user-reported regressions fixed] should generally be "within a week", preferably before the next rc.""[1] – we are way past that.

Note, I assume this will break things for people where the change in question improved things. But I suspect he in a situation like this Linus prefers to go back to what was "normal" before the culprit was merged. If we are unsure about this I guess we should get him involved to clean this up.

Ciao, Thorsten

WiFi no longer works on Pinebook Pro after upgrade to kernel 6.18. It appears firmware fails to load:
