Version-Release number of selected component (if applicable): kernel-3.12.5-301.fc20.armv7hl How reproducible: Every time Steps to Reproduce: 1.

Looks like it's blowing up in ethernet code: function is in drivers/net/ethernet/ti/cpts.c
(In reply to Christopher Wawak from comment #0) > Steps to Reproduce: > 1. Boot stock BeagleBone Black system on 3.12.5-301 kernel. I can reliably reproduce this behavior when I tell the a-b-c to boot in "debug" mode. When the system boots normally, I can't reliably reproduce this error. There is an Ethernet cable plugged into the BeagleBone Black, and the cable is also plugged into an active network port.

(In reply to John Dulaney from comment #1) > Looks like it's blowing up in ethernet code: function is in > drivers/net/ethernet/ti/cpts.c It's not actually ethernet code at all. It's a PTP time sync driver. I've disabled this in git now as well as swapped out the cpsw patch with the upstream kernel fix. It will be in what ever kernel is newer than 3.12.6-300. In the meantime you can get the kernel-3.12.6-300.fc20.armv7hl.rpm kernel from http://pbrobinson.fedorapeople.org/arm-kernel/ dated Dec 28th which has the fix.
I have just filled a similar bug: https://bugzilla.redhat.com/show_bug.cgi?id=1048478 Also, with the latest kernel from rawhide (vmlinuz-3.13.0-0.rc6.git0.2.fc21.armv7hl) I don't get Ethernet either.
Created attachment 845623 [details] serial log booting 3.13.0-rc6 with abort on non-line fetch Hi Florin, For me, the kernel-3.12.6-300.fc20 linked by Peter works well, there is no error and network and usb work. As Peter points out, the kernel after 3.12.6-300 in the update repository will be the one that is fixed. For 3.13 I got the same as you, kernel-3.13.0-0.rc6.git0.2.fc21 from fedora-rawhide-kernel-nodebug still has the problem (maybe because master still has CONFIG_TI_CPTS=y). 3.13 log is attached.
*** Bug 1048478 has been marked as a duplicate of this bug. ***
Zach, It is interesting - my results with 3.12.6-300 are repeatable. And I'm starting from power-off. Is there a possibility we have different revisions of the chip My /proc/cpuinfo says: CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x3 CPU part : 0xc08 CPU revision : 2
It's an issue with the driver for the CPTS component of the NIC, try the kernel mentioned in comment 4 or wait for the next kernel which will likely be 3.12.7
Hi, Peter. I am experiencing this same bug with a roll-your-own Linux build using kernel version 3.12.10. After reading the comments associated with this bug (1043271), I disabled CONFIG_TI_CPTS as suggested in my kernel, but the non-linefetch error and oops still occur with heavy Ethernet traffic. I can't find explicit details of how you resolved this bug. If your code changes involved more than just setting CONFIG_TI_CPTS=n in the kernel, can you please share the details? Thank you, Desiree
please don't set a needinfo for a closed bug with a custom kernel
