So it's relocating the compressed kernel and decompressor from 0x80A000C0-0x8112BA40 to 0x8152C700-0x81C58080 and then failing. Does the QEMU version also do similar? On the off-hand, I'm not sure why it should fail. I assume that you've tried the other decompressors and they work fine on the same setups? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
