Re: Bug in 2.6.29 ide-cd: Kernel freeze: bisected + unacceptableworkaround

Hello Borislav,

I got even no output over the serial console when the kernel freeze. So
I tried your patch and the complete log from the boot to the freezing state
is attached below.
One additional observance: Without your hotfix starting /usr/sbin/hald
takes quite longer (about 3 to 5 seconds) compared to about a half second
with your hotfix. Same behaviour with the commit found by bisect: Before
that commit hald starts fast and from that commit hald takes some seconds.
To me it looks like that probing (?) by /usr/sbin/hald maybe left the ide-cd
in some erroneous state which result in a freeze after about 2 minutes?
