I had my system running up for about one month without any issues, and

So I have upgraded to 2.6.22-rc4-mm2 in hope it might fix it, but I just
got another oops (uptime 4d) [see attached file]
You "upgraded" from -stable series kernels (2.6.19.2 / 2.6.20.6 /
2.6.21.1) to a -mm kernel, which is anything but :-)
On the one hand, I really like that we're getting testers for -mm
kernels, but on the other hand, my good and honest side would
recommend you to install stable kernels (2.6.x.y versions) on
production systems, if you really care about uptimes.
my config hasn't changed in any way to the previous kernels.
This doesn't look like the same oops you were getting persistently
with 2.6.21.1 ... you could try upgrading to 2.6.22-rc6 (without -mm)
too, if the oops in 2.6.21.1 was occurring too frequently in your setup;
possibly it has been resolved in the 22-rc series.
