I finally managed to tar the kernel and install it but it doesn?t boot the system and now I get the following error: - Failed to get ramdisk from boot Unexpected trap Error code, optional 0x0 Code segment 0x28 Flags register 0x10046 Retyrn %rsp 0xc0cfd0 Return %ss 0x8 There is no stack trace and I get a similar error right below the one above when the system tries to backtrace and it says Nested trap Press any key to reboot. I will investigate further into the problem but if you think you have any pointers to resolve this issue please do let me know. Thanks and regards Bhaskar. -- This message posted from opensolaris.org
