It doesn't occur on i686 hardware.

I mean it doesn't occur with a 32bit kernel. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is the current development DRM we're using for R6xx/R7xx bringup together with AMD/ATI. The sources are not open yet, because of IP issues that have to be resolved, but it's supposed to get upstream at some point of time. We *do* have the sources, of course. Next test: tried this on a different machine - no reboots. I assume that the engineering sample has some BIOS issues... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Is the "new" drm code properly asking for the interrupt from the kernel core?

radeon DRM is always setting an irq handler .irq_handler = radeon_driver_irq_handler, It's initialized for soft IRQs (created by the command processor when the command in the ring indicates to issue an IRQ), and (eventually) for vertical blanks, but that is turned off if no DRI client is active. I don't exactly know how the preinstall, postinstall, uninstall functions of a device driver are called. But the card doesn't issue any IRQs, because the reboot happens when the system is perfectly idle.

It looks like the message at boot is different, which is very odd.

I think I loaded drm with debug=1. That might make a difference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't have the original system any more due to a harddisk crash, so I cannot verify that the old kernel still locks up, but I'm testing on a RV770 that used to crash in few seconds only, and it's running fine for several minutes now, including our 3D test application. Thanks, Greg! BTW - are there any pointers to some documents or mails what was going wrong here? For sure I don't understand why PCI resource handling can have such devastating effects... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
