Description David Atkins 2024-02-11 11:36:41 UTC

If I have a single card it works and I can attach it to an access point, if I have two cards both fail to operate.

Same base line issue as my report https://bugzilla.kernel.org/show_bug.cgi?id=219380

This issue (essentially QRTR clashing if the same instance ID is being used multiple times in one machine) is known since 2022 and there was no actual effort to fix it since the start of 2023.

I've posted a write-up regarding this to the ath11k mailing list: https://lists.infradead.org/pipermail/ath11k/2024-October/006481.html

I wouldn't get my hopes up, though.

Luckily, I'm also using WCN7850 in my setup, so I'll check if the RFC mentioned last is compatible with it. If it is, there's at least a workaround for some hardware out there.

Hello, I have exactly the same issue after I bought second card. Does here any update?
