I use it, I was thinking about the Linus' git branch. If you use that, head Makefile won't tell you the whole truth (it won't tell you which commit you are on). > I haven't noticed any UML > git branch... Right, we queue our patches with quilt and send them through -mm. Jeff publishes his *development* quilt tree on UML homepage. > 2) I'm still worried about this halt problem on amd64, can You give me > some tips I could track it down??

SMP does not work; when Jeff will announce "SMP support ready" then it will be possible to start using it again. Otherwise, if you enable debug info and recompile it, try attaching gdb to the process using 100% cpu (type gdb $vmlinux_binary $pid) and then type bt at the prompt. While recompiling, under "Kernel hacking" try enabling every debug option (excluding "kobject debugging" and a few others) - this is what I have on testing kernels, for reference (comes from a GIT head kernel): CONFIG_PRINTK_TIME=y CONFIG_ENABLE_MUST_CHECK=y # CONFIG_UNUSED_SYMBOLS is not set CONFIG_DEBUG_KERNEL=y CONFIG_LOG_BUF_SHIFT=15 CONFIG_DETECT_SOFTLOCKUP=y CONFIG_SCHEDSTATS=y CONFIG_DEBUG_SLAB=y CONFIG_DEBUG_SLAB_LEAK=y CONFIG_DEBUG_RT_MUTEXES=y CONFIG_DEBUG_PI_LIST=y CONFIG_RT_MUTEX_TESTER=y CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_MUTEXES=y CONFIG_DEBUG_RWSEMS=y CONFIG_DEBUG_SPINLOCK_SLEEP=y CONFIG_DEBUG_LOCKING_API_SELFTESTS=y # CONFIG_DEBUG_KOBJECT is not set CONFIG_DEBUG_INFO=y # CONFIG_DEBUG_FS is not set CONFIG_DEBUG_VM=y CONFIG_DEBUG_LIST=y CONFIG_FRAME_POINTER=y CONFIG_UNWIND_INFO=y # CONFIG_FORCED_INLINING is not set CONFIG_RCU_TORTURE_TEST=m # CONFIG_CMDLINE_ON_HOST is not set # CONFIG_PT_PROXY is not set # CONFIG_GCOV is not set > thanks a lot for Your patience with me... > nik -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
