hidnplayr: network irq handler calls KernelAlloc, KernelAlloc fails and returns zero, network irq handler tries to write to zero address, in context of the system process it leads to #PF.
1. The handler should not crash in situations with low memory - if KernelAlloc returns zero, it probably isn't possible to do much, but at least fail politely.
2. Something is leaking memory allocated with KernelAlloc - KernelFree calls are missing or have invalid arguments. While theoretically it could be due to some other system components, I suspect the network layer.

CleverMouse: Yes, what you say is what I was thinking as well.
I did not make any comments yet because I need to review code. I should not even be using KernelAlloc, but NetAlloc instead.

Since #5561 i8255x driver should no longer leak memory, and fail graciously when out of resources.
Correct handling of "out of resources" situation remains to be done.

I8255X: Out of resources!

Everything is fine! Freezing disappeared, as puddles mushroom from the rain under the bright summer sun.

popovpa: Currently, chain reaction of problems occurs when network card says it's out of resources.
I must figure out how to handle this situation properly, and write this code in the driver.

I'm in the process of setting out Kolibrios on my PC. Downloaded it yesterday and have it running - dual booting without any issue between mxlinux and kolibrios.

I cannot get networking to work. Have tried a number of different nics.

The PC currently has a I82559 based intel nic and a 3com 3c905B.

The debug says the following:

I8255X: Out of resources!
3C59X: This device is not auto-negotiation capable.

Both nics work without any issue when I boot mxlinux.

When booting Kolibrios, I've tried each nic individually, to rule out any resource conflicts, and get the same results as I mentioned above.
