Hi Martin,
Attached are bootlogs of the same system booting the same kernel with
only one difference: the inclusion of the "sleep 5" patch in the initrd.
I generated the initrd's using :
mkinitramfs -o sleep.img 2.6.21-2-sparc64-smp
mkinitramfs -o nosleep.img 2.6.21-2-sparc64-smp
If you diff the logs, you can clearly see that the scsi bus scan for
esp0 is still ongoing as local-top/mdadm tries to assemble all MD arrays
which cause it to fail and the system to hang. All the sleep does really
is give esp0 enough time to finish scanning it's bus and bring all
devices up before having mdadm do it's thing.
I can't help but think that there must be a cleaner way to wait for the
bus scan to finish before handing control over to mdadm.
Cheers,
Eric
