Description Ben LaHaise 2003-01-02 18:29:51 UTC
On a system with SCSI disks and the primary ide controller disabled in the BIOS,
the ide driver takes far too long to time out an open operation on /dev/hda. 
This results in lilo taking forever to run.

[root@localhost etc]# time dd if=/dev/hda of=/dev/null bs=1k                   
dd: opening `/dev/hda': No such device or address                              
real    0m14.828s                                                              
user    0m14.780s                                                              
sys     0m0.030s                                                               
[root@localhost etc]#

During this operation is modprobe/insmod running somewhere ?
