If I do just apply fix2.patch onto latest git tree v3.15-rc3-113-gba6728f then I do get after a while :
* Starting sshd ... [ ok ]
* Starting local
net.core.warnings = 0 [ ok ]
Kernel panic - not syncing: do_syscall_stub : PTRACE_SETREGS failed, errno = 3

which is a big improvement because before it crashes immediately after few seconds.
After applying both fixes the test case runs w/o a crash till now.
