Summary: Radeon card reports wrong temperature when switched off Product: Drivers Version: 2.5 Kernel Version: 2.6.38-rc5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: mail@3v1n0.net CC: mail@3v1n0.net Regression: Yes
In previous versions of the kernel (I've tested the 2.6.37 version) when the I switched off the radeon card using vga_switcheroo libsensors was correctly reporting that the radeon temperature was 0° (or invalid).
This doesn't happen any more using the latest kernel, in fact (after the commit 20d391d72519527d2266a0166490118b40ff998d, I figure) when my radeon card has been switched off (or after a suspend/resume cycle) sensors indicates:
radeon-pci-0100 Adapter: PCI adapter temp1: +2147355.6°C
This is obiouvsly impossible.
