Created attachment 307591 [details] dmesg output On my HP Elitebook 8560p the ATI drivers fail with a DMA error leaving behind Xorg in a unkillable state: root 3798 99.0 0.1 81152 12844 tty7 Rs+ 10:24 2:03 /usr/bin/Xorg :0 -br -verbose -logverbose 7 -auth /var/run/gdm/auth-for-gdm-Gqu8wg/database -nolisten tcp vt7 Only a restart helps. The solution is to turn intel_iommu off using "intel_iommu=off" at command line or not building the intel_iommu in the kernel. This happens with ati-drivers 12.2 and 12.3 (I did not test older ones). This happens on kernel 3.2.12-gentoo and 3.3.0-rc7 (as I got some other problem with 3.4 I was not able to test this so far) This does not happen with the open source driver. relevant part of dmesg (I upload complete one as a attachment) [ 36.563299] [fglrx] ATIF platform detected with notification ID: 0xd0 [ 36.812625] fglrx_pci 0000:01:00.0: irq 60 for MSI/MSI-X [ 36.813111] [fglrx] Firegl kernel thread PID: 3922 [ 36.813287] [fglrx] Firegl kernel thread PID: 3923 [ 36.813472] [fglrx] Firegl kernel thread PID: 3924 [ 36.813612] [fglrx] IRQ 60 Enabled [ 36.990811] [fglrx] Gart USWC size:1280 M.

Not a gentoo bug. I will add an ewarn to the ebuild about this and i will resolv this bug as upstream once done. Thank you for the report. By the way, if you want you can report to the unofficial AMD bugzilla http://ati.cchtml.com/ and add a "See Also" link here. I will also try to reproduce the issue on my computer, but I doubt i will be able to. I already enable intel iommu as a module and it doesn't get autoloaded, so I guess i haven't the hardware to test with.
I changed my mind. I will leave the bug open. It is far better then 2 lines of an ewarn. Googling the error should quickly point here. Btw I just uploaded 12.4 in the X11 overlay if you want to test it.
The same problem with 12.4 :-(
Closing this bug, as 12.2 is not available in tree anymore. Please reopen, if you can reproduce with a recent version.
