I'm getting a lot of stuff like this on my ec2 instance:
kernel: [141720.410047] INFO: task kjournald:14019 blocked for more than 120 seconds.
kernel: [141720.410205] INFO: task flush-202:112:2005 blocked for more than 120 seconds.
.......
my os is ubuntu 10.10 2.6.35-22-virtual #33-Ubuntu SMP Sun Sep 19 21:05:42 UTC 2010 x86_64 GNU/Linux
I was advised to install a new kernel, but unsure how to proceed.
