This takes the form of:\n\n`smsc95xx 1-1.1:1.0 eth0: kevent 0 may have been dropped`\n\nafter which the wired ethernet stops working.  Wifi continues as usual; devices associated with the Pi when in AP mode can ping it and each other, but (obviously) no packets are forwarded to the wired network.  This severely limits its use as a wifi AP.\n\nkevent 0 would appear to be EVENT_TX_HALT, which is triggered when the interrupt handler has too much work to do, and hands the processing off to the kworker thread.  For some reason, although the worker thread seems to be executing correctly, the condition isn't cleared, probably in the hardware.  I've no idea why this bug seems to be tickled by bridging it with the wifi.  I've now reached the end of my kernel knowledge.\n\nThere's a thread [here](https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=160021) on the forums.\n\nThanks.\n"},"comment":{"url":"https://api.github.com/repos/raspberrypi/firmware/issues/comments/296770861","html_url":"https://github.com/raspberrypi/firmware/issues/673#issuecomment-296770861","issue_url":"https://api.github.com/repos/raspberrypi/firmware/issues/673","id":296770861,"user":{"login":"popcornmix","id":1053730,"avatar_url":"https://avatars0.githubusercontent.com/u/1053730?v=3","gravatar_id":"","url":"https://api.github.com/users/popcornmix","html_url":"https://github.com/popcornmix","followers_url":"https://api.github.com/users/popcornmix/followers","following_url":"https://api.github.com/users/popcornmix/following{/other_user}","gists_url":"https://api.github.com/users/popcornmix/gists{/gist_id}","starred_url":"https://api.github.com/users/popcornmix/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/popcornmix/subscriptions","organizations_url":"https://api.github.com/users/popcornmix/orgs","repos_url":"https://api.github.com/users/popcornmix/repos","events_url":"https://api.github.com/users/popcornmix/events{/privacy}","received_events_url":"https://api.github.com/users/popcornmix/received_events","type":"User","site_admin":false},"created_at":"2017-04-24T17:58:02Z","updated_at":"2017-04-24T17:58:02Z","body":"@mangodan2003 One cause of random corruption would be too high an overclock or an insufficient power supply.\r\nAre you overclocking?
