> Kernel oopses on early boot stages (boots normally with boot_delay=10). > rc5-git8 Please find which kernel this failure starts in. Start by testing 2.6.30.stable so we can tell if this is a regression in the current RC. What is the difference between the two dmesg? they have the same cmdline, neither has boot_delay, and neither dmesg shows the oops. The fact that boot_delay=10 makes the problem go away suggests some sort of race condition. Is 10 the smallest value of printk_time that works, or is it a random value? Do you still see the oops with CONFIG_PRINTK_TIME=n? Do you still see the oops with maxcpus=1? Do you still see the oops with "acpi_serialize=1"?
