I think we should upgrade to 2.7 and use the patch. > this afternoon, played a while linuxbios + tiny kernel on l1_2pvv. find something interesting.
vmlinux 2.6.18.1 in buildrom A. built from on my laptop with opensuse 10.3 64bit B. built from my workstation with Suse 10.0 pro 64bit A is much bigger than B, Also A doesn't work mkelfImage + LinuxBIOS, but B work with mkelfImage + LinuxBIOS then I tried 2.6.24-rc3 from git, it works with A and B. maybe some gcc default setting difference about stack checking cause that. BTW, what is the kernel version in LAB now? YH -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
