Hi Backports Project Team, Thank you for providing the project. Me and my team are trying to use Backports to install ath11k on our system but we have met some problems. We have successfully built the Backports Project and installed modules on our system. When I boot up the system, it reports some issues like: [ 3.815040] ath11k_pci 0000:06:00.0: BAR 0: assigned [mem 0xb3200000-0xb33fffff 64bit] [ 3.815094] ath11k_pci 0000:06:00.0: enabling device (0000 -> 0002) [ 3.815314] ath11k_pci 0000:06:00.0: qcn9074 hw1.0 [ 3.815316] ath11k_pci 0000:06:00.0: failed to register to mhi bus, err = -22 [ 3.815352] ath11k_pci 0000:06:00.0: failed to register mhi: -22 [ 3.815459] ath11k_pci: probe of 0000:06:00.0 failed with error -22 I have checked the code, and found it was because the driver could not get Length of the MHI MMIO region. So I checked the version of those modules, and I found packages like mhi.ko having a version of 5.15, which was built from backports, like pic 1 in the attachment. And for packages like ath.ko and ns.ko, they have a version of the kernel version, like pic 2 in the attachment. We are using SLES 15 SP4 with kernel version of 5.14.21-150400.22-default, and backports-5.15.58-1. If you need more information, please contact me and I will reply the email as soon as possible. Thank you! Best, Liu, Kainan(he/him) Software Engineer Surgery Engineering, China GE Healthcare T +86 15611095678
