Hi There!

I am currently using
Linux ecam.anagramm.de 2.6.21-rc5-g9a5ee4cc #4 Mon Apr 2 21:31:53 CEST 20=

07 ppc e500 GNU/Linux

on an mpc8540 embedded powerpc system.

The system was running fine for many days and weeks without any problems.
However, just a few minutes ago I noticed a single clicking sound of the =

harddisk

(like a head recalibration), so I checked the system.
I couldn't connect to it via ssh anymore, but via a serial console I got
at least endless messages as shown below...
After a reboot, everything looks fine again but the kernel log grew up
to several MBytes. I pasted the hopefully interesting part below.

Any ideas of what could be wrong there? I think there could be a problem
in the gianfar network driver. Or is there a physical problem with the PH=

Y

(a Marvell MV88E1111)?

Any recommendations of how to debug that thingy?

There were some workarounds in the e1000 driver to address some issues
with some Marvell 88E parts, so you might want to check those out.

The system time is wrong, because the I2C realtime clock cannot be read
on this system due to some kernel misconfiguration which I didn't care ab=

out.

Thank you in advance,
