Subject: Re: [PATCH] pcie AER: don't check _OSC when acpi is disabled

Would you like to submit the Driver Test Cases to LTP ? Or, if you have
your Driver test cases written in C, we can port to LTP and have it
inside the LTP package.
You can also check out the following links for more info, and can always
ping me for anything:
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/device-drivers/,
http://ltp.sourceforge.net/documentation/how-to/ltp.php?
