Host is in all tests
Dual-opteron amd64
Kernel 2.6.14-skas3-v9-pre7
Gentoo
Glibc 2.3.5-r2
Gcc 3.4.4-r1
Guest kernel is 2.6.16-rc5, with patches from uml homepage as of february
24, minus user-desc.
Guest kernel was compiled in 64-bit:
make mrproper ARCH=um
make defconfig ARCH=um
make menuconfig ARCH=um (only change was to enable tt)
make linux ARCH=um
Root_fs is a clean, unmodfied amd64 gentoo stage3.
Bootlogs are attached as separate text files.
TT: Idle hang, but also steals my keybord. Never saw this before. Had to
ssh into the box and kill X in order to get keyboard back. This happens
both when running uml output/input to console and to xterms. End result
is an idle hang anyway.
Skas0: Busy hang, won't boot
Skas3 (mode=skas3): kernel panic
Skas3 (noprocmm as noted on list): busy hang, same as skas0
Anyway, end result is that I still haven't been able to kick up uml in
64-bit mode with a home-compiled guest kernel. I must be doing something
seriously wrong. :-)
