Hello,
A firewall of ours recently went tits up (2.4.19). It was still routing
traffic but when I connected to SSH for example the SSH banner would not
appear, it looked like all userspace was dead.
When we looked in the logs there was this. Presumably the hardware is
broken. But I wonder if anyone can confirm this? Thanks!

Turns out to be a 2bit ECC error. The machine is a dell power-edge 350.

A while ago I mentioned it would be nice to get the ECC drivers
cleaned up and included. Any yays or nays to getting this stuff
done sometime ?
Yes it's a feature, but it's also just extra drivers.
Decisions decisions...

Put that way, any driver is a feature, but that's not the point AFAIK.
So go with more drivers...
