Subject: Patch to add 'printk's at *_abort and IDLEIMMEDIATE.
Date: Mon, 12 Jul 2004 11:23:45 -0400 [thread overview]
Message-ID: <40F2AD01.B6EDA948@verizon.net> (raw)
The following patch adds printk calls to the ide *_abort functions and after
each OUTB(WIN_IDLEIMMEDIATE,IDE_COMMAND_REG) call so that there is a record
of these important error conditions in the log. I'm not absolutely certain
that KERN_WARNING is the correct message level. KERN_ERR or higher might be
more appropriate.
