I m using Fedora Core 2 (2.6.8.1) on XEON 2.2GHz SMP Machine with 8GB RAM. When I boot my system with the kernel 2.6.5 or on 2.6.8.1 without SMP and HIGHMEM64G support it boots fine, but when I boot with SMP and HIGHMEM64 enabled on 2.6.8.1 or 2.6.5, the booting process becomes tooo slow i.e. took almost 20 or minutes to boot. The Same kernel configuration on the other machine having same hardware configuration (except have 2GB RAM in other machine not 8GB) works well. The machine creating problem is working fine with kernel 2.4.25 or so ............ Please do help me .......... Fawad Lateef __________________________________ Do you Yahoo!? New and Improved Yahoo!
