Bug#860534: Similar bug

[bugs.report.filter@ipnoz.net]

Hi.

I get a similar bug, but my system doesn't freeze, it directly reboot 
without any warning. I looked into all my logs files, nothing is 
reported by the system.

I've got the same GPU as the guy who reported this bug : AMD/ATI Juniper 
XT [Radeon HD 5770]
