Kernel Booting Slow - initramfs - Ubuntu 7.04 Kernel 2.6.20
Hi
I've had this issue of a really slow boot time for a while on my Acer Travelmate 2500 ...
[ 41.278169] checking if image is initramfs... it is
[ 105.948785] Freeing initrd memory: 6770k freed
Can anyone explain the massive delay - the full dmesg output is below (highlighted in red, sorry, quite far down). It also seems to take a while to early unpack the initramfs ...
[ 27.601270] Early unpacking initramfs... done
[ 40.348883] ACPI: Core revision 20060707
This is really frustrating me!
Searched everywhere and can find no info on this, any insight would be much appreciated. It boots just fine after that initial delay.
Thanks and regards.
