After some testing around, we noticed that it is enough for the kernel to boot correctly if we limit the kernel to use 4GB of memory. If the kernel has 6GB, I directly get error messages like: SCSI device sda: 143299800 512-byte hdwr sectors (73369 MB) sda: Write Protect is off sda: got wrong page sda: assuming drive cache: write through SCSI device sda: 143299800 512-byte hdwr sectors (73369 MB) sda: Write Protect is off sda: got wrong page The disk array controller is of type GDT8114RZ and has the most current firmware version. The box has 4 Xeon CPUs, and physical 6 GB of memory. The /-device is on the controller in question. The full log (for 4 and for 6 GB) is put up on http://neualius.turmzimmer.net/~aba/6GB Any hints for me how I can use the full 6 GB of memory (and/or what I should try out to find the bug)?
