boot log error

branch: master
commit: d7b248e715d99766bf8602ff9f038f8b0afa5e78

1. Set following sentences in local.conf to GPLv3
#####
INCOMPATIBLE_LICENSE = "GPLv3"
#####
2. Build core-image-minimal and core-image-basic
3. Start up target after build is finished

Notice error in boot sequence: screenshot attached

NOTE: After about 5 minutes the boot sequence resumes and the image boots successfully.

Which MACHINE?  I tried with qemuarm and it worked, but when I tried an x86-64 I got a load of failures, looks like grep is segfaulting all over the place during user space initialization.

In the future it would be useful to get a full output of the startup, you can do this with the runqemu serial arg, and then cut and paste from your terminal.
Comment 2 Stoicescu Cornel 2013-03-01 09:12:54 UTC 
The machine in my case is qemux86-64.

Full boot log attached. Thank you for your patience.
Comment 5 Saul Wold 2013-03-05 16:20:44 UTC 
I have confirmed that the grep command is segfaulting for the non-gplv3 version.

Build with INCOMPATIBLE_LICENSE = "GPLv3", boot system, you might need to include gdb or other debugging tools.  This might require some special handling, due to the INCOMPATIBLE_LICENSE issues.

Very weird problem where "setlocale()" call returns a string in an unreachable memory space. Continue investigating. Backtrace is below, in case it rings a bell.
