While playing minecraft after not having rebooted in a number of days, it complains that the kernel rejected CS, see dmesg for more info. dmesg shows:
[389509.644744] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!
[389509.645383] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!
And sometimes, a whole bunch more that I will include at the end of this message. At first I thought I had a memory fragmentation issue so I forced a compaction but the errors persist. At the time, free and /proc/buddyinfo show:
psusi@faldara:~/Videos$ cat /proc/buddyinfo
Node 0, zone DMA 1 1 1 0 2 1 1 0 1 1 3
Node 0, zone DMA32 5644 34509 26973 298 54 1 0 0 0 0 0
Node 0, zone Normal 337 589 164 56 48 25 13 11 4 0 0
psusi@faldara:~/Videos$ free -m

Mem: 3930 3160 770 32 15 577
- -/+ buffers/cache: 2567 1362
Swap: 2047 499 1548
So it looks to me like I have plenty of free memory, and even in some of the higher order chunk sizes ( this was not the case prior to forced compaction ), so why is radeon complaining -ENOMEM?
