Load average when system is booting : 65 !

	Hello,

	I have build a new 2.6.23.1 kernel to fix some trouble with
2.6.21.3. 
When I have rebooted my U2E (2*Uii300, 2 GB), system says :

Waiting for /dev to be fully populated
Uniform CD-ROM driver Revision: 3.20
sr 0:0:6:0: Attached scsi CD-ROM sr0
sd 0:0:0:0: Attached scsi generic sg0 type 0
sd 0:0:1:0: Attached scsi generic sg1 type 0
sr 0:0:6:0: Attached scsi generic sg2 type 5
done(timeout)
Adding 3903664k swap on /dev/md0.  Priority:-1 extents:1
across:3903664k
EXT3 FS on md1, internal journal
kjournald starting.  Commit interval 5 seconds

	This stage take two or three minutes, and load average
reachs 65 ! I 
have restarted my 2.6.21.3, but with same result. This
workstation runs 
a uptodate testing release. I don't understand my mistake.
When this box 
is booted, it works fine.

	My U60 boots without any trouble with a similar kernel and
the same 
distribution.

	On the same box :

,retrans=2,sec=sys,addr=rayleigh 
0 0
Root fermat:[/] >

	I don't understand why /dev/md1 is the only disk returned
by df... Why 
/boot and rayleigh:/export/home do not appear ? Of course, I
have 
verified that /boot and NFS disks are both accessible.

	Any idea ?

	Regards,

	JKB

	U60 is a PCI station, U2E, a Sbus one. Can this trouble
come from this 
difference ?
