I am having a problem with getting 8GB of RAM to work with the 2.6.5 kernel that Red Hat uses in their new Fedora Core 2 test3 release. Yes, not vanilla, but hopefully close enough (otherwise I can try it with a custom kernel). The systems (I'm testing on two mostly identical systems) that are experiencing the problem have these specs: Motherboard: Tyan K8W (S2885) Processors: 2 x Opteron 248 Memory: 8 x 1GB BIOS version: 1.02 (2-3-2004 - latest available) SCSI card: Adaptec 29320 About 80% of the time I get this error when booting: ... RAMDISK: Compressed image found at block 0 crc error VFS: Cannot open root device "<NULL>" or unknown-block(3,2) Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on unknown-block(3,2) The other 20% of the time it boots up fine, but that's not enough consistency for these computers final task (beowulf compute nodes). Also I haven't really stressed the kernel on these boots. The systems seem to work fine if I pull out half the memory so that they only has 4GB of RAM. I've also tested a similar setup using a Rioworks Arima HDAMA board with 8GB of RAM and it worked. So I'm led to believe that this is some kind of driver issue or possibly a bios problem... Any help/ideas are of course appreciated.
