Bug ID: 214670
Summary: MCS9900-based parallel port card unsupported
Product: Base System
Version: 11.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: f...@fuz.su
It seems that due to an oversight, parallel port cards with the MCS9900 chipset
are not supported by the FreeBSD kernel. After adding the following patch and
adding appropriate device hints, the card is supported and works fine:

};
Please add this patch to the FreeBSD kernel so the card is supported
out-of-the-box.
