--- From: sos@login.dkuug.dk (S|ren Schmidt) Subject: IDE-disk hangs - solution/patches NetBSD/FreeBSD Summary: fixes for lost interrupts with IDE disks Keywords: hanging-disk, IDE-disk, lost-interrupt Due to "popular" demand I'm posting these patches to NetBSD/FreeBSD instead of mailing them around the world :-) As many have found out there is a problem when using IDE disks on FreeBSD. Following is a patch that fixes the problem with lost intterrupts. Both fixes is based on a patch posted here some month ago by Stefan Behrens?? (sorry I've lost the original article). But anyway it works (for me :-). Basically it does a timeout on lost interrupts, starting the operation again and logging and error message on the console. It additionally makes the allready present while loop timeouts independent of CPU speed, and adds minor numbers for easy access to dos partitions. |
