Apologies for the unclear image. My camera phone was all that I had handy during the crash.
Comment 2 Ankur Sinha (FranciscoD) 2013-08-17 22:03:46 EDT
Appears to be also be reported in other distributions. This link says it's a "divide by zero" error:



I haven't been able to try a newer kernel than 3.10.x yet, since it crashes immediately on activating wifi.  A hard shutdown caused disk errors last time and I hade to reinstall Fedora from scratch :/

The same kernel panic occurs to me with wifi enabled. Previous kernels (kernel-3.10.5-201.fc19.x86_64 and kernel-3.10.4-300.fc19.x86_64) are working good, the 3.10.6 kernel was the first that produced the same kernel panic as this 3.10.7 kernel.

Same here. kernel-3.10.5-201.fc19.x86_64 and kernel-3.10.4-300.fc19.x86_64 work good in my machine.
Comment 7 Cristián Rojas 2013-08-20 09:50:28 EDT
This affects me as well. I'm running Fedora 19 on a Dell Inspiron 14z. The issue appears when I try to authenticate to a wireless network. I currently use the 3.10.5, 3.10.6 and 3.10.7 kernels, and the issue occurs when I use the 3.10.6 and 3.10.7 kernels.
Comment 8 Stas Ashirov 2013-08-20 11:18:51 EDT
Confirm. Kernel panic on my MacBook Air, Broadcom BCM43224, kernel-3.10.7-200.fc19.x86_64. Previous kernels are working good.

New update to kernel 3.10.9-200.fc19.x86_64 restored sanity. This version is working good for me. Thank you!
