Hi all,
I am building a linux kernel image from the source code and trying to
boot it in gem5 full system mode. But the system hanged at "disabling early
console" forever. For some reason, I have to use the 2.6.18 kernel version.
I downloaded from kernel.org. The following is the debug info of booting
the system. Any help will be greatly appreciated. Thanks
