Subject: revert request "ide: skip probe if there are no devices on the port (v2)"
Date: Sun, 28 Mar 2010 16:27:28 -0500 [thread overview]
Message-ID: <20100328212728.GA2674@spacedout.fries.net> (raw)
Now that I have 2.6.34-rc2 booting it no longer detects the cdrom
drive. That is looking at the kernel messages, partition dump, and
after booting hdparm etc does not find the drive. I expect it is
because the cdrom is a slave drive without a master on that ribbon.

ide: skip probe if there are no devices on the port (v2)
In ide_probe_port() skip probe if ide_port_wait_ready() returns -ENODEV
and print error message instead of debug one if it returns -EBUSY.
v2:
Fix the default 'rc' value.

-------------------------------
fixes the problem. That branch
'for-2.6.31' of git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6
was merged at d614aec4752f8c61b2e7cb77806b6bd59aa50836
boot output, no hdd mentioned
Again I'm giving it a bad root partition so it dumps the partition
table at the end of the messages and I can hibernate and resume
my other kernel.
