On bott: printk twice for SATA drive under libata? (SMP related?)

[Kalin KOZHUHAROV <kalin@thinrope.net>]

Hi, there.

Not sure if this is a bug or not, but is there any reason to "find"
a SATA disk drive twice during boot? Here is a snippet of dmesg:

This is a dual-core P4 system (single CPU), that might be the
problem if it is considered a problem. Almost vanilla-2.6.13.1
(sk98lin and mppe-mppc patched)
