After i had added some extra memory in my Linux server with Debian Etch, the following error occurred during starting up the system: "no such device open sock (?)" or something like that. After that message, the system hangs. Within the BIOS setup screen i could see that the system recognizes all the memory banks within the server, so that's ok. I am sure that the memory chipsets are ok for the server, because Dell advised me to use the ones i've bought. So it seems that the current Linux kernel (AMD64) does not recognise the extra memory. Now i want to know, how to solve this problem. I am thinking about installing a different Linux kernel, but on the moment i don't know which one. (The total memory of the server will be 8 GB) Can anyone give me advise what to do in this situation? Thanks in advance!
