Re: [uml-devel] does a x86 (== 32 bit) uml image works at a 64 bit system Gentoo hardened Linux ?

[Toralf F. <tor...@gm...>]

FWIW I recompiled glibc now with debug info.

Now the linux boot goes further till this step :

...
NET: Registered protocol family 10
sit: IPv6 over IPv4 tunneling driver
NET: Registered protocol family 17
Key type dns_resolver registered
Initialized stdio console driver
Console initialized on /dev/tty0
                                console [tty0] enabled
console [tty0] enabled
                      bootconsole [earlycon0] disabled
bootconsole [earlycon0] disabled
                                Initializing software serial port version 1
console [mc-1] enabled




gdb gives :
tfoerste@t44 ~ $ pgrep linux | xargs -n1 -i{} sudo gdb /home/tfoerste/devel/linux/linux {} -n -batch -ex 'bt'

warning: Cannot call inferior functions, Linux kernel PaX protection forbids return to non-executable pages!

warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
