Yep, I am using ccache, same sources -> same binary. addr2line -i now says: /var/local/src/linux-2.6.git/linux-2.6/mm/slub.c:1648 /var/local/src/linux-2.6.git/linux-2.6/mm/slub.c:1662 Strangely the EIP is the same even after rebuilding with debug info. Since tip/master supports the latency tracing features, I won't dig further into the linux-next problem now (we'll know tomorrow if the commits in tip solve the boot problem).
