What I have personally seen is a long delay in bus_alloc_resource() on some older Dell machines (desktop and laptop, both under 500Mhz). If I apply the attached patch, I see between 15 and 20 rows of identical output, and each call to b_a_r takes a noticeable fraction of a second (i.e. the cursor spends most of its time after an IRQ, not after a 'y' or 'n'.) The delays probably add 45 seconds total to the boot time. Newer systems will just generate 4 or 5 lines total for the entire boot process. -- Dan Nelson dnelson_at_allantgroup.com
