Is this a switchable graphics laptop (i.e., discrete and integrated graphics) by any chance? If so, you'll likely need the switcheroo stuff in 2.6.34. No it's a discrete laptop card:

Any new? I see mani radeon/kms commits but noone fixes. Does Xorg works without kms ? Yes. I'm trying to track down how userspace gets the ROM contents via libpciaccess to fix in in the kernel driver, but I don't know how AtomBIOS is involved in this process Please test with 2.6.34-rc* change have been made there and it might work with it. Tested with 2.6.34-rc5, it doesn't work. read(image) returns 0 instead 0x55 in pci rom read code Please attach dmesg of 2.6.34-rc5 with KMS and failing rom Exactly the same of the 2.6.33 which i've already posted Created attachment 26157 [details]
Linux 2.6.34-rc5 syslog
Note that I've added a WARN()in drivers/pci/rom.c to debug the issue
Please attach drivers/gpu/drm/radeon/radeon_bios.c it seems different from the one upstream and it's useless to add warn to rom.c. Created attachment 26165 [details]

Please add a printk at the begining of r700_read_disabled_bios to make sure this function is use. I have added:
printk("[DBG]: %s\n", __func__);
and got:

possible fix
Does this patch help?
Yes it fixes. Thanks Sorry I was booting with user mode setting. With KMS the error is still. I've added some more printk to the bios get code: [drm] radeon kernel modesetting enabled. radeon 0000:02:00.0: setting latency timer to 64 [drm] initializing kernel modesetting (RV710 0x1002:0x9553).

What does your kernel command line look like? The vesa framebuffer seems to cause issues.
