Hi, Starting UML like this:
./vmlinux rootfstype=hostfs rw ignore_console_loglevel con=xterm init=/bin/bash Results in unpredictable behaviour, most of the time an xterm flashes on my screen but the process aborts with only "Aborted" on the console where I ran the command, sometimes the xterm remains there but frozen, sometimes the xterm spews this warning non-stop: [ 12.790000] WARNING: CPU: 0 PID: 908 at include/linux/thread_info.h:128 sigsuspend+0xab/0xc0() [ 12.790000] CPU: 0 PID: 908 Comm: deferwq Tainted: G W 4.2.5+ #37 [ 12.790000] Stack: [ 12.790000] 6243fe78 600753f2 6243fe68 00000009 [ 12.790000] 00000000 605cc5f4 6243fe88 605cf5a7 [ 12.790000] 6243fee8 60040f3d 6243fec8 600511eb [ 12.790000] Call Trace: [ 12.790000] [<600511eb>] ? sigsuspend+0xab/0xc0 [ 12.790000] [<605cc5f4>] ? printk+0x0/0x94 [ 12.790000] [<60029f0b>] show_stack+0xdb/0x1a0 [ 12.790000] [<600753f2>] ? dump_stack_print_info+0xd2/0xf0 [ 12.790000] [<605cc5f4>] ? printk+0x0/0x94 [ 12.790000] [<605cf5a7>] dump_stack+0x2a/0x2c [ 12.790000] [<60040f3d>] warn_slowpath_common+0x9d/0xf0 [ 12.790000] [<600511eb>] ? sigsuspend+0xab/0xc0 [ 12.790000] [<605d0030>] ? __schedule+0x0/0x610 [ 12.790000] [<60051140>] ? sigsuspend+0x0/0xc0 [ 12.790000] [<60051140>] ? sigsuspend+0x0/0xc0 [ 12.790000] [<605cc5f4>] ? printk+0x0/0x94 [ 12.790000] [<6004111c>] warn_slowpath_null+0x1c/0x20 [ 12.790000] [<600511eb>] sigsuspend+0xab/0xc0 [ 12.790000] [<6002e7ca>] winch_thread+0x16a/0x250 [ 12.790000] [<605cc5f4>] ? printk+0x0/0x94 [ 12.790000] [<6002e660>] ? winch_thread+0x0/0x250 [ 12.790000] [ 12.790000] ---[ end trace 6fe139d6fbc54eb3 ]--- Some (hopefully relevant) bits from my .config: $ grep 'UML\|PTY\|TTY\|xterm' .config CONFIG_UML=y # UML-specific options CONFIG_UML_X86=y # UML Character Devices CONFIG_PTY_CHAN=y CONFIG_TTY_CHAN=y CONFIG_CON_CHAN="xterm" # CONFIG_UML_SOUND is not set CONFIG_TTY=y CONFIG_UNIX98_PTYS=y CONFIG_LEGACY_PTYS=y CONFIG_LEGACY_PTY_COUNT=256 # CONFIG_TTY_PRINTK is not set # CONFIG_UML_RANDOM is not set # CONFIG_UML_WATCHDOG is not set # UML Network Devices # CONFIG_UML_NET is not set Thanks, Vegard ------------------------------------------------------------------------------ Presto, an open source distributed SQL query engine for big data, initially developed by Facebook, enables you to easily query your data on Hadoop in a more interactive manner.
