Hi! I (and other) had problems, that may be related to this. Can you look into it ? What happened was : linux boot had a delay of 10..30..90..infinite seconds, depending on command line length and certain disk related BIOS settings. GRUB was the loader. The delay went away after disabling CONFIG_EDD. It was also "fixed" by downgrading the BIOS version. It would be really cool if you could inject some wisdom in the issue ;-) For details, see the LKML archives : "EDD code causes long boot delay" "[PATCH 2.6.9-rc3-mm2] EDD: use EXTENDED READ command, add CONFIG_EDD_SKIP_MBR" "[PATCH 2.6] EDD: add edd=off and edd=skipmbr options" Kind regards, David Balazic
