lilo kernel params failure

lilo kernel params failure

[dant]

I have been strugling with this for some time now.

It looks like a failure of lilo to pass kernel params ( append="...." )
But we have been through the code and fail to find a reason.
this happens with the lilo-mtd in the cvs /patches area and we have
patched 21 with the same results.
We are using DoC  2000 with kernel 2.4.2 though this has been happening
for months really.
Anyone have any ideas?

I sent a patch here few months ago for lilo-mtd, i havent checked if it
got applied. Attached again, just for case. 
Another option is to use lilo available from m-sys (this one is a bit newer 
version if i recall correctly).

I have a patch for LILO 21.6.1. It works well for me with kernel 2.4.0.

Bye.
