sorry i don't know how to run bt, and i don't have gdb.
my hdd info:
/dev/sda1 # another linux : LMDE(linux mint based on debian)
/dev/sda2 # swap
/dev/sda3 # bootstrap-linux (using musl-cross as cross compiler instead of bootstrap-linux built-in).
and more additional information about latest git-version musl libc. git pull right now.
result:
# cd util-linux-2.23/.libs
# ./mount /dev/sda1 /mnt
EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
< 30 - 40 seconds waiting without return to shell>
mount: /mnt: filesystem mounted, but mount(8) failedOperation timed out // <-- this is weird.
#
and umount gets segfaults randomly..
# umount /mnt
traps: umount[9444] general protection ip:7f9c48e618fb sp:7fff72447b88 error:0 in libc.so[7f9c48e16000+72000]
Segmentation fault.
maybe i should have to build new bootstrap-linux again using new musl libc.
