As requested by Andrew, I did a kernel bisect and tracked the patch which introduced the problem due to the following commit from the linux git branch:
$ git bisect bad f8924e770e048429ae13bfabe1ddad9bf1e64df7 is first bad commit commit f8924e770e048429ae13bfabe1ddad9bf1e64df7 Author: Alexey Starikovskiy <[email protected]> Date: Fri Apr 4 23:42:21 2008 +0400 x86: unify mp_bus_info Signed-off-by: Alexey Starikovskiy <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> :040000 040000 7b8f52df457e110e772966ff11f2b7c1a217281e 99a49c71b7db70dccf17f974513554090a9e97aa M arch Seems like the patch adds some sort of ISA related check, but this seems to break my Dells which have ISA/EISA. Hope this helps. I have verified that checking out the patch just before this one works fine on the machines. I haven't heard back from Andrew yet, but he mentioned passing it off to the proper people to look into it. I will update this post when I hear more. troubled -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
