Description of problem: I was booting my lenovo ideapad s12. it appeared to stop booting with the fedora logo half displayed for a few minutes. I pressed shift and it carried on. dmesg has the following: [ 5.998506] SELinux: initialized (dev cgroup, type cgroup), uses genfs_contexts [ 217.741035] INFO: rcu_sched_state detected stalls on CPUs/tasks: { 1} (detected by 0, t=211742 jiffies) [ 217.741072] sending NMI to all CPUs: [ 217.741095] NMI backtrace for cpu 0 [ 217.741106] Modules linked in: wmi i915 drm_kms_helper drm i2c_algo_bit i2c_core video [ 217.741148] [ 217.741163] Pid: 0, comm: swapper Not tainted 3.1.0-7.fc16.i686.PAE #1 LENOVO 20021,2959/MoutCook [ 217.741191] EIP: 0060:[<c04244d6>] EFLAGS: 00000086 CPU: 0 [ 217.741216] EIP is at default_send_IPI_mask_logical+0x83/0x87 [ 217.741232] EAX: 00000006 EBX: 00002710 ECX: fffff000 EDX: 00000c00 [ 217.741248] ESI: 00000006 EDI: 00000002 EBP: f4421e68 ESP: f4421e60 [ 217.741270] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 217.741279] Process swapper (pid: 0, ti=f4420000 task=c0a74fa0 task.ti=c0a32000) [ 217.741286] Stack: [ 217.741291] c0a87100 c0a87280 f4421e70 c042454b f4421e80 c042465a c097b5fa f7203518 [ 217.741312] f4421eb0 c04999ac c098b136 00000000 00033b1e 00000092 00000001 c0a87280 [ 217.741332] c0a87180 00000000 00000000 c0a74fa0 f4421ebc c0499da3 00000000 f4421ed0 [ 217.741353] Call Trace: [ 217.741366] [<c042454b>] default_send_IPI_all+0x26/0x3c [ 217.741377] [<c042465a>] arch_trigger_all_cpu_backtrace+0x44/0x66 [ 217.741389] [<c04999ac>] __rcu_pending+0x1c1/0x282 [ 217.741400] [<c0499da3>] rcu_check_callbacks+0x72/0x9d [ 217.741411] [<c0453a04>] update_process_times+0x32/0x5d [ 217.741422] [<c046d4dc>] tick_sched_timer+0x72/0xa7 [ 217.741434] [<c0462773>] ?

Steps to Reproduce: 1. boot Actual results: boot hangs Expected results: boot to login screen Additional info: in the past I have used the boot flag, "nolapic_timer" to prevent issues of hanging until there is keyboard interaction. but I was not currently using it.
I believe there were some fixes upstream in the 3.2 or 3.3 kernel for an issue similar to this. Do you have this problem with the 3.2.7 or newer kernels?
[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.
i have removed nolapic_timer from my boot options, and with the 3.2.10 kernel it seems to not hang any more. I'll close this for now, and hope that it does not show up again. thanks
