(See my other similar post http://marc.info/?l=linux-kernel&m=130221292724436&w=2) This time the problem is generated by Bluetooth device. Often just only several messages are printed - and then machine suspend - so the log usually contains only several such message - if at all - however today with debugging and serial console logging - I've seen several times - that suspend resulted in endless unbreakable loop. As a workaround - one could just disable BT device: "echo disable >/proc/acpi/ibm/bluetooth" Here is the log: [ 0.000000] Linux version 2.6.39-rc2-00005-gf04d4dc (kabi@linux) (gcc version 4.6.0 20110331 (Red Hat 4.6.0-2) (GCC) ) #119 SMP PREEMPT Wed Apr 6 15:27:55 CEST 2011 [ 0.000000] Command line: ro root=/dev/sda2 selinux=0 kmemleak=off lockdep.prove_locking=0 lockdep.lock_stat=0 SYSFONT=latarcyrheb-sun16 LANG=cs_CZ.UTF-8 KEYTABLE=us systemd.log_level=info systemd.log_target=kmsg systemd.sysv_console=true console=ttyS0,115200n8 console=tty drm.debug=0xe ..
