The linux kernel 6.11 and 6.12 seems to have a bug in the mt7921e driver for MediaTek bluetooth adapters, which is in my Lenovo e14 laptop.
So this bug appears to be in Debian Trixie (which the bug isn't in Debian Bookworm 12.
.
The bug causes the laptop not to be able to resume from suspend. This bug also occurs on Debian bookworm 12.8 when using 6.11 or 6.12 kernels from backports. (But no bug when using the stock Bookworm kernel, which is 6.1 I think).
The following lines are in my journalctl that may be relevant to the resume from suspend issue:As long as I disable bluetooth, the bug goes away and the laptop can resume from suspend fine. As soon as you re-enable blueooth, the bug re-appears.
Thanks
