Description Ingvar Hagelund 2013-08-19 08:16:16 UTC
Created attachment 787925 [details]
Output from dmesg just after boot

Description of problem:
While booting and doing things that hits kernel space (I haven't debugged this much, but at least while trigging LVM), the kernel issues a lot of warnings

Version-Release number of selected component (if applicable):
3.11.0-0.rc5.git3.1.fc20.ppc

How reproducible:
Always

Steps to Reproduce:
1. Boot 3.11.0-0.rc5.git3.1.fc20.ppc on an G3 iBook
2. Watch the boot log or output from dmesg

Actual results:
See attached file

Additional info:
I know 32bit ppc is not officially supported by Fedora for powerpc, but in case anyone is interested, I've reported it here.

Comment 1 Benjamin Herrenschmidt 2013-08-19 11:15:40 UTC
Very very odd ... we local_irq_disable() in gup so we shouldn't hit that warning unless the in_atomic() test is failing. I'll try to have a look later this week.

This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle.
Changing version to '20'.

This needs fixing upstream.
