I updated to 13.1 recently; before update I removed nVidia driver and thought I look at how nouveau behaves. It appears to work (even with thermal management) but dmesg is flooded on boot with messages similar to [ 51.124732] nouveau E[ PFB][0000:01:00.0] trapped write at 0x01013cc970 on channel 0x00007ed0 [unknown] BAR/TEXTURE/IN reason: PAGE_NOT_PRESENT [ 51.125042] nouveau E[ PFB][0000:01:00.0] trapped write at 0x01013ccbc0 on channel 0x00007ed0 [unknown] BAR/TEXTURE/IN reason: PAGE_NOT_PRESENT [ 51.125076] nouveau E[ PFB][0000:01:00.0] trapped write at 0x01013d0bb0 on channel 0x00007ed0 [unknown] BAR/TEXTURE/IN reason: PAGE_NOT_PRESENT [ 51.125809] nouveau E[ PFB][0000:01:00.0] trapped write at 0x01013d0df0 on channel 0x00007ed0 [unknown] BAR/TEXTURE/IN reason: PAGE_NOT_PRESENT [ 51.125849] nouveau E[ PFB][0000:01:00.0] trapped write at 0x01013d88a0 on channel 0x00007ed0 [unknown] BAR/TEXTURE/IN reason: PAGE_NOT_PRESENT Not sure whether they indicate some issue ... should I open bug report?
