The "*ERROR* Failed to allocate GEM object" message didn't appear
for ~three hour load, but now I get the following kernel fault:
(typed from picture)
kernel: supervisor trap page fault, code=0
Stopped in pid 18756.1 (cc1plus) at netbsd:amap_wipeout+0x77: movl
e9c,e1aa5f1c) at netbsd:uvm_unmap_detach+0x41

0) at netbsd:ext1+0x178
sys_exit(c888b9c0,e1aa5f68,e1aa5f60,8,213,e1aa5f60,1,e1aa5f68,0,0) at netbsd:sys
syscall() at netbsd:syscall+0x127
--- syscall (number 1) ---
But maybe this is yet another problem on memory shortage?
I'll continue to check if the original radeon gem error occurs or not.
