I compiled a vanilla 2.6.12.4 kernel, enabled EARLY_PRINTK and rebooted with earlyprintk=vga. The kernel didn't display any extra information before the delay.
$ uname -a Linux quince 2.6.12.4 #1 Fri Aug 12 13:02:40 PDT 2005 i686 GNU/Linux $ cat /proc/cmdline root=/dev/md0 ro nodma earlyprintk=vga $ grep EARLY_PRINTK /boot/config-2.6.12.4 CONFIG_EARLY_PRINTK=y
I tried Alt-SysRq-T but there was no response. SYSRQ is enabled. $ grep SYSRQ /boot/config-2.6.12.4 CONFIG_MAGIC_SYSRQ=y
