Hi, I have the following machine http://www.intel.com/isp/servers/lb440gx.htm with Dual P3 550's and 2GB of RAM in them. Redhat 6.2 with its stock kernel 2.2.14-5 detects the 2GB of RAM and boots up happily. When I compile 2.2.17 with 2GB RAM, I get the following error on boot up request_module[block-major-8]: Rootfs not mounted VFS: Cannot open root device 08:01 Kernel Panic: VFS: Unable to mount root FS on 08:01 However, compiling the same kernel with the only change being to limit the kernel to using only 1GB RAM causes no such problems [all other configuration variables are the same]. I get the same results with 2.2.16 also Can others confirm/deny my findings ? Any workarounds ? -- Yusuf Goolamabbas [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
