Eric, With the latest change that make vmlinux to be elf64 and make bzImage do switch to 64bit long mode, the kernel started via kexec can not get VGA console. but the serial console works well. I wonder if the setup.S is skipped in bzImage via kexec path. or i missed sth? #!/bin/bash ./kexec -t bzImage -l bzImage_2.6.22_k8.1 --command-line="apic=debug acpi_dbg_level=0x00000007 pci=routeirq snd-hda-intel.enable_msi=1 ramdisk_size=65536 root=/dev/ram0 rw ip=dhcp console=tty0 console=ttyS0,9600n8" --ramdisk=mydisk8_x86_64.gz YH - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
