Today's Next failed to boot on x86_64 box with following messages. PNP: No PS/2 controller found. Probing ports directly. serio: i8042 KBD port at 0x60,0x64 irq 1 serio: i8042 AUX port at 0x60,0x64 irq 12 mice: PS/2 mouse device common for all mice cpuidle: using governor ladder cpuidle: using governor menu TCP cubic registered registered taskstats version 1 Freeing unused kernel memory: 1360k freed Write protecting the kernel read-only data: 4980k At this point the machine hangs. The corresponding code looks to be the following snippet from init/main.c static noinline int init_post(void) __releases(kernel_lock) { ...... if (sys_open((const char __user *) "/dev/console", O_RDWR, 0) < 0) printk(KERN_WARNING "Warning: unable to open an initial console.\n"); ^^^^^^^^^^^^^^^^ hangs here ^^^^^^^^^ ...... } Next 20090723 was fine. (20090724 failed due to a failure during 8250 init.) Complete boot log and config attached.
