Same problem here when suspending my Fedora/Gnome desktop. This occurs with a TP-Link TL-WN 821 V3 stick (USB WLAN stick with internal PCI bridge) using the ath9k driver. $ lsusb -s 001:008 ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287]
This bug is not easily reproduceable. It seems like it only occurs in some states when the USB WLAN device is getting hot due to buggy power management. In this state the connection times out or drops or (rare case) I get a kernel panic. This bug seems to be a result of the Atheros controller overheating.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.11.1-200.fc19. Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those.
This bug is still somehow present for me with 3.11.1-200.fc19 kernel but different: Setup: TL-WN 821 V3 WLAN device Steps to reproduce (now easily reproducible) : 1. transfer much data over WLAN device until it overheats 2. try to suspend-to-ram 3. watch what happens What happens: Fedora does not suspend but lock the screen being unresponsible for a while. After ~10 seconds I can login again as if I just had my gnome session locked. dmesg reports call traces (see attachment). What should happen: Suspend btw: this kernel makes the TL-WN 821 V3 device running much more stable: It is able to download >2GB before overheating (was about 50MB before).
