kernel bug or coincidence

Mon Mar 15 15:50:30 UTC 2010

hello,

I have experienced a failure like this twice on same day and once in another day

Call Trace:
...
[<c0408f17>] kernel_thread_helper+0x7 ...

I have scrolled up and found that there is some sata errors

ata1: limiting speed to
ata1.00: SATA link up ...
...
this happened twice and it happened only with the updated kernel

my yum logs shows

Feb 15 00:35:35 Installed: kernel-PAE-2.6.30.10-105.2.23.fc11.i686

I'm now using the previous kernel for days and I've not encountered that error
and DeviceKit does not report any problem

my current kernel is
uname -r
2.6.30.10-105.2.16.fc11.i686.PAE

here are images of the problem
