Created attachment 883027 [details] This machine does not exibit the problem Description of problem: ======================= BUG: soft lockup - CPU#0 stuck for 22s! [someprocess:2773] Followed by different types of hangs. This happens often while browsing the Internet with Firefox and happens even more often if using Opera. Happens almost always when running (eg. a fedora boot CD) with qemu-kvm Happens often on heavy software operations like when the dropbox client reindexes many files. On one machine I had to disable it, because it locks up tha machine every single time it starts a reindex. Happens often on heavy rsync transfers (rsync backups of VMs). Happens only on certain machines and with recent kernels. Previous kernels on the same machines do not display any problems. When it happens the whole machine goes haywire. Network soon stops responding, x stops respopnding etc etc. The only symptom in the logs is the line: BUG: soft lockup - CPU#0 stuck for 22s! [someprocess:2773] No other anomalous logs can be found. In testing I disabled Virtualbox in order to ensure an untainted kernel Version-Release number of selected component (if applicable): kernel 3.13.8-200.fc20.x86_64 Additional info: ================ See attachments of "fpaste --sysinfo" of affected and unaffected machines

*********** 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 20 kernel bugs. Fedora 20 has now been rebased to 3.14.4-200.fc20. Please test this kernel update (or newer) 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.
Yep Still happening on kernel 3.14.4-200.fc20. I also noticed that on some machines it happens only on 32bit kernels.

Before upgrading my kernel from 3.16.7-200 → 3.17.2-200 I was getting these soft lockups on system boot more times than not (system-udevd was usually the curplit). After upgrading I don't get the lockups anymore but I do have another problem: I've booted 8 times, and 5 out of those 8 the drivers for my dvb device failed to load properly. Running lsusb would hang, and the system would hang on shutdown. On a tangently related note: Why doesn't the system immediately reboot after all the filesystems are unmounted? After that point nothing that any shutdown program does can have any effect on the system.
More info: My problems with 3.17.2 were definitely related to USB somehow. They were affecting my dvb device because it is a usb device. More importantly I upgraded my kernel 3.17.4-200.fc20.x86_64 and I'm getting soft lockups on boot again, as well as kernel panics. I see a new kernel has been released. I'll try that and report back.
3.17.6-200 suffers from the same problems as 3.17.4-200
