Xcb lib hangs in xcb_wait_for_reply (cf. detailed stack trace below) :
#0 0x000000308eed93ed in poll () from /lib64/libc.so.6
#1 0x000000308e20a5d2 in ?? () from /lib64/libxcb.so.1
#2 0x000000308e20b9ff in ?? () from /lib64/libxcb.so.1
#3 0x000000308e20bb02 in xcb_wait_for_reply () from /lib64/libxcb.so.1
-generate a project like this:
/wrlinux-6/wrlinux/configure --enable-board=intel_x86_64 --enable-rootfs=glibc-core --enable-kernel=standard --enable-build=production --enable-reconfig --enable-parallel-pkgbuilds=16 --enable-jobs=16 --with-template=feature/archiver --with-license-flags-blacklist=GPLv3,LGPLv3,GPLv3+,LGPLv3+
- use attached default-image.bbappend file
- apply the patch for LIN6-9883
the platform hangs will occur and a backtrace starting like this is created:
