I'm having this same error with my new Sapphire Radeon 9250 256MB and setting
BusType to "PCI" allows Direct Rendering to work. I can only assume direct
rendering is broken with AGP on my hardware.
I am using the very latest Debian unstable (2006-09-21) with latest Debian
2.6.17 SMP amd64 kernel. I am using the latest git kernel modules (drm.ko and
radeon.ko).
Hardware:
2 x Opteron 244 (SMP, amd64 kernel & userland)
MSI K8T Master2-FAR (VIA K8T8000 chipset)
Sapphire Radeon 9250
4 x DDR-333 512MB
Here's 'dmesg' from when I get the 100% CPU usage:
[drm] Initialized drm 1.0.1 20051102
ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 16 (level, low) -> IRQ 177
mtrr: type mismatch for 4000000,2000000 old: write-back new: write-combining
[drm] Initialized radeon 1.25.0 20060524 on minor 0:
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Device is in legacy mode, falling back to 2.x
agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode
agpgart: Putting AGP V2 device at 0000:01:00.0 into 1x mode
[drm] Setting GART location based on new memory map
[drm] Loading R200 Microcode
[drm] writeback test succeeded in 1 usecs
During the 100% CPU, I get this over and over in strace on X:
--- SIGALRM (Alarm clock) @ 0 (0) ---
rt_sigreturn(0xe) = -1 EBUSY (Device or resource busy)
ioctl(6, 0xc0406429, 0x7fffacceffc0) = -1 EBUSY (Device or resource busy)
Thanks for any help!
