Can you please explain how to suppress 'quiet' during boot time? thanks Pom On Wed, Jul 28, 2010 at 4:38 AM, Alan Bartlett a...@elrepo.org wrote: On 28 July 2010 02:21, Franchisseur Robert robert.franchiss...@lmd.jussieu.fr wrote: On our Dell laptops E6400 or E6500 the boot process is very long.

Slow boot with Kernel 2.6.18-194.x.y on SL5.4
Hello, On our Dell laptops E6400 or E6500 the boot process is very long. It takes ~ 40 seconds between: Redhat NASH and INIT: if we suppress 'quiet' we see that the problem is after the line : device-mapper : dm-raid45 : initialized V0.25941 Waiting for driver initialization and it seems the system is waiting some timeout. Does anyone know if there is a Bios or kernel parameter to change to have a faster boot ?
