Subject: sleep before boot panic
Date: Sun, 6 Jan 2008 19:08:42 +0100	[thread overview]
Message-ID: <200801061908.43010.bernd-schubert@gmx.de> (raw)

Hi,

I just switched to libata (pata) on my laptop and the immediate panic made it 
impossible to figure out why my boot partition wasn't available.
After applying this little patch I could check boot printk output and then saw 
everything was properly recognized and only scsi-disk support was missing.
