Title:
Crash due to BUG: Bad page map in process X & BUG: Bad
Public bug reported:
[impact]
The kernel update from 3.13.0-153 to 3.13.0-155 has introduced a
regression as shown:
[9.490655] java: Corrupted page table at address 7f3ef3967000

[9.494401] Bad
I started a kernel bisect between Ubuntu 3.13.0-153 and Ubuntu
3.13.0-155. The kernel bisect will require testing of about 6-8 test
kernels.
I built the first test kernel, up to the following commit:
6f4b6df5cb10508e0c1c81c3884ca1afca98c8e2
The test kernel can be downloaded from:
Still no hangs/freezes/crashes in the last week so looks like issue
either fixed in upstream kernel or was fixed in Skype/VCC!
