With the 2650 configured with 2 1GB sticks memtest86 started reprting errors almost immediately. "Terrfic!" I thought, "this is my problem!" The address seemed suspicious though: 0007ffedc80 (2047.8MB) is where all the errors were reported. I decided to let it run all the way through but it froze at 34% of the first test. Memtest86 also said it did not support this chipset when I tried to dink with advanced options. So, I replaced the ram with 4 512MB sticks I had laying around from a different Dell machine. I booted memtest86 again and what do you know.... errors @ 0007ffedc80, with completely different RAM. So obviously these results are fishy. Someone replied to me off-list and said the only way they could get their Dell 2650 stable was by running 2.4.28. -- john On Wed, 1 Dec 2004 11:16:17 -0800, Chris Wright wrote: > * John Newman (cachehit@gmail.com) wrote: > > Nov 24 21:34:10 ptscorp-nis01 kernel: Unable to handle kernel paging > > request at virtual address 01000004 > > Possible bad memory.
