My Thinkpad X32 (r100, Mobility M6) can't suspend or hibernate with KMS using the "radeon" driver. "radeonfb" and the VESA fallback (no KMS) are both fine. It seems to be the same bug as: https://bugs.freedesktop.org/show_bug.cgi?id=38554 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=583120 The problem manifests in the console and inside X11, and with 0 or 3 in /proc/sys/kernel/acpi_video_flags. "radeontool light off" to disable the backlight doesn't help, either (no VGA plugged in) Looking at drivers/video/fbdev/aty/radeon_pm.c, I notice it sets a D2 sleep mode for my X32: BUGFIX("IBM Thinkpad X31/X32", PCI_VENDOR_ID_IBM, 0x052f, radeon_pm_d2, NULL), Which I suspect is what allows "radeonfb" to work for me But I can't find the corresponding quirk in drivers/gpu/drm/radeon/, so I now believe a missing quirk is the cause of this problem with the "radeon" driver. I poked around but couldn't figure out what changes to make to the "radeon" driver to enable the corresponding, but I'm willing to test patches. Setting "dynpm" in /sys/**/power_method didn't seem to change things, either. Help greatly appreaciated. Thanks I've mainly been using the X32 as a server this decade so didn't use suspend/hibernate so I didn't investigate until recently (because my netbook died). _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
