Greetingz!
Working on a Dell XPS 630 w/ an nVIDIA RAID controller using 2 x 500GB in a Stripe (RAID0).
I'm seeing a 5-minute delay right after the following line;
Code:
[ 0.532448] rtc_cmos 00:05: setting system clock to 2012-04-25 21:03:12 UTC (1335387792)
[ 83.337852] INFO: rcu_sched_state detected stalls on CPUs/tasks: { 0} (detected by 1, t=20705 jiffies)
Note: Even though it skips from 0.53 to 83.3, it waits for about 4.5 to 5 minutes.
Is this what you're seeing too? (Note that I ripped out the 'quite' and 'splash' options from the GRUB2 boot-line)
