--- Begin Message ---Package: src:linux Version: 5.16.18-1 Severity: normal Dear Maintainer, * What led up to the situation? I have spurious wireless disconnectionsafter upgrading to linux-image-5.16.0-6-amd64. Downgrading to linux-image-5.16.0-5-amd64 definitely solves the problem. The iwd message is: "Received Deauthentication event, reason: 4, from_ap: false". Same problem using wpasupplicant (no pertinent messages however). I did not found any relevant message in the kernel log. Disconnections and reconnections occur during big files download or watching video with medium or high definition. I tested the 2.4 and 5 Ghz band with same result. It happens with an Atheros AR9462 adapter using the ath9k driver. I could test without any problem an usb adapter with rtl8192cu driver but the bitrate is lower. * What exactly did you do (or not do) that was effective (or ineffective)? I bisected the stable kernel tree. I finally obtained the following commit as the designated culprit: swiotlb: rework "fix info leak with DMA_FROM_DEVICE" commit aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13 I not 100% sure that this is the offending commit since it is not easy to test each kernel in a reasonable time (I performed some iso downloads to trigger the problem and this maybe not reliable). Moreover I am unable to link DMA problem to wireless problem (poor knowledge) * What was the outcome of this action? However I tested a 5.16.18 version with this commit reverted and I did not meet any problem running it.
