(Sorry maybe you receive that twice as parts of the email seemed to bounce back) I asked, if it s possible to confirm that this is a BIOS issue and how to workaround it... BTW: suspend resume works fine with vesa (and under windows xp as well) Chris -----Original Message----- From: Benjamin Herrenschmidt [mailto:benh@kernel.crashing.org] Sent: Saturday, November 11, 2006 2:49 AM To: Rafael J.

Hi, We've just got the appended report. Could you please have a look at this?
There are many possible reasons for that. The most likely is that the BIOS isn't bringing the chip back on resume, causing radeonfb to crash when trying to access it. Ben.

Screen stays black and nothing works anymore, no capslock light, no ctrl alt sysreq b etc. I tried all kind of things vbetool, passing acpi_sleep=s3_bios,s3_mode to the kernel. Nothing seems to work. You can see dmesg output and lspci -vv output here http://christianhoffmann.de/temp/radeon.log http://christianhoffmann.de/temp/lspci.log Thanks a lot for any input. Chris PS: I use kernel 2.18.1 + patch for radeonfb from http://bugzilla.kernel.org/attachment.cgi?id=9408&action=view
