Intel Centrino 6205 iwlwifi crashed during heavy load k5.7.1
Last modified: 2020-06-22 13:25:06 UTC
Hi there, during the past hour or so I've been hitting the WiFI pretty hard by uploading some large ISO files via CIFS / GVFS to the NAS. It usually fluctuates between 2 and 4 megabytes/sec upload. Performance suddenly dropped to a few KB/s, and then the WiFI disconnected. dmesg appears to indicate a crash. I'm attaching what I hope is useful information. Thanks a lot!

Just read this, I assume it's the issue I experienced?

The bug in 5.7.1 was rather crashing at boot, so it's possibly a different issue.
In anyway, try a later version of 5.7.x kernel in OBS Kernel:stable repo.
Thanks Takashi. I doubt it's reproducible consistently, so I'll just wait for the standard Tumbleweed kernel updates. I'll close this bug for now, and I'll re-open it if the same bug hits again.
