I use fedora core 4,when I rebooted from linux(not from windows or BIOS),it will hang after the system POST before grub display the stage 1.5 on the screen,so I must reboot again from there using CRTL+ALT+DEL I don't know whether this belongs to grub or belongs to the linux reboot changes from 2.6.8 and 2.6.9 This only happens in rebooting from Linux kernel within 2.6.10-2.6.13-rc4(not from BIOS or windows).when I use grub to handle boot ,the grub will hang after the system POST,must reboot again from BIOS to boot correct in the grub menu. It only happened *reboot* from Linux,if I directly cold boot everything is ok,or if I reboot from windows it 's booted ok also I tested the older kernel version from 2.6.13-rc4 to 2.6.8 .I found the 2.6.8 and the 2.6.9 worked well without above reboot_from_linux_with_hang_after_POST,and the 2.6.10-2.6.13-rc4 were all have The motherboard is GIGABYTE GA8IPE-1000 ,865PE chipset INTEL ICH5R, prescott 3.0E I wait somebody to report this bug for a long time and to be fixed but seldom people meet and seems like none fix this.
