kernel log when i run some ogl apps (unigine-*;some 3d games; even
google-chrome)
I've gzipped log because it has ~ 14MB.
main part are bazillion lines like that:
<3>[ 414.876442] radeon 0000:01:00.0: GPU fault detected: 146 0x0fe32004
<3>[ 414.876446] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR
0x000021FF
<3>[ 414.876448] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x03020004
<4>[ 414.876450] VM fault (0x04, vmid 1) at page 8703, write from CB (32)
<3>[ 414.876455] radeon 0000:01:00.0: GPU fault detected: 146 0x0fc32004
<3>[ 414.876457] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR
0x00000000
<3>[ 414.876458] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x00000000
<4>[ 414.876460] VM fault (0x00, vmid 0) at page 0, read from unknown (0)
Usually my PC doesn't respone but sometimes like for unigine-sanctuary i can
see graphics corruption for a while. When i downgrade libdrm everything works
like before.</pre>
