rootdelay=90 not works ?
I have one of old machines, on centos, wuth grub and kernel 2.4.20.
on one not-so-great day it after reboot show "cannot open root device, kernel panic!". i try various thinks, check all hardware, and my "now"
idea is involve a rootdelay before kernel try mount root partition, because before that i cannot see strings like a "ATA0: founda sata disk ...."
that is P4 system on 845 or 865 chipset with pata and sata on board. times agoo all work fine, reboots too, but yesterday something changes.
system is on only sata disk. i try to in grub menu put rootdelay=10 rootdelay=20 and even rootdelay=90 - no changes, all things do as fast as without "rootdelay" options.
i boot in knoppix via live dvd, mount boot partition of systemdisk, and edit grub.cfg - adding to end of kernel line rootdelay=90 - also not any effect.
anyeone have a similar experience \ ideas what i can do, for waiting to kernel detect system sata disc before try to mount root partition?
