Hi,

Today I have freshly installed F12 on a x86_64 PC
(with four 1TB hard disks in a BIOS/JMicron Raid10).

I keep getting afore mentioned lines in my /var/log/messages, followed by
many more lines with complicated hex numbers and a long kernel trace.

The system keep runnings, although I seem to notice occassional system 'hic-ups';
I mean, unusual slower responses. However, the system does not crash nor come
to a grinding stand-still....

Nevertheless, I find these messages quite annoying!
Here is the output of `grep "INFO: task " /var/log/messages`:

Nov 23 19:08:20 localhost kernel: INFO: task pdflush:72 blocked for more than 120 seconds.

Nov 23 19:14:20 localhost kernel: INFO: task kjournald2:1061 blocked for more than 120 seconds.


Is this a general problem with F12?
Or related to my 64 bit installation?
Or related to the BIOS/Raid10 configuration?

Thanks,
Rob.
