Hi, Since the changes in the VM subsytem to use 4M pages, X dies when loading a background in 24 and 32 bit mode. Initially I thought this might just be an SMP problem, but I had the same failure with a UP kernel. The SVGA server only supports linear address and MMIO so I couldn't try it with those features shut off. It appears that when the Xserver maps a region larger than 4M, pmap_addr_hint rounds addr to the next 4M boundary which causes the crash. Comment out pmap_addr_hint and the Xserver run fine in 32 bit mode. dave adkins adkin003@gold.tc.umn.edu
