I finished installing Fedora Core 3 on my new server, and it crashes every now and then - so far I noticed it happened when GNOME was coming up (at some network stage) and then within GNOME. I went through the dell utilities and it found no hardware problems, but when the server crashes / freezes i get the amber / orange light flashing in front and back. The server is a Dell Poweredge 1850 and has the the following specs: 2 X 2.8GHz/1MB Cache, Xeon 800MHz Front Side Bus for PowerEdge 1850 2GB DDR2 400MHz (4X512MB) Single Ranked DIMMs Riser,ROMB,PCI-X,PE1850 Embedded RAID - PERC4 EmbeddedIntegrated 2 X 146GB,U320,SCSI,1IN 10K;PE1850 2 X INTEL PRO-100S W/IPSEC,NIC (intel fast ethernet lan controller pci slot 2 & 1) 2 X Intel pro 1000 mt gigabit ethernet adapter onboard A friend told me they had trouble with the onboard nics on a different but similar Dell, so I bought the PCI ones through dell turns out he had trouble with broadcom's. Has anyone else had similar problems, or does anyone have any advice on what to troubleshoot? Thanks.
