Subject: Re: NetBSD 3 SCSI broken - msg#00006List: os.netbsd.ports.mac68kSadly I think that very few people use the mac68k systems for long times anymore, especially for servers. In my case I use a portable, so 8 hrs or so is the max uptime. It's too bad that it has broken though. cheers bruce On Sun, Apr 16, 2006 at 01:51:08PM -0700, John Klos wrote: > Hello, > > After many months of testing things when I've had spare time, I can now > say definitively that Quadra class machines (605, 650, 800) will > eventually lock up under heavy SCSI usage.

Previous Message by Date: click to view message previewNetBSD 3 SCSI brokenHello, After many months of testing things when I've had spare time, I can now say definitively that Quadra class machines (605, 650, 800) will eventually lock up under heavy SCSI usage. This does not happen under NetBSD 1.6.x. I've tried several different kinds of SCSI drives, with and without command queueing, syncronous and asyncronous, the same drives with 1.6 and 3, and I have two long term test machines which have significant uptime with 1.6.x and can be locked up by cvs'ing src and pkgsrc at the same time.

Not sure, but it's definitely repeatable, and I've tried four different machines with as many different hard drives now. Ideas, anyone? John Next Message by Date: click to view message previewRE: NetBSD 3 SCSI brokenI've tried building all the NetBSD 3 packages on two different Quadra 840 systems (one has 32 MB memory, the other has 128 MB, both have 18 GB Seagate SCSI disks), and invariably they will lock up after about a week, but not at the same point. I even tried a spare system board, same result. An SE/30 also locked up, after about 3 weeks. If someone knows a way to capture the state of the systems after a hang for debugging, please let me know. -Stan -----Original Message----- From: port-mac68k-owner@xxxxxxxxxx [mailto:port-mac68k-owner@xxxxxxxxxx] On Behalf Of John Klos Sent: Sunday, April 16, 2006 3:51 PM To: port-mac68k@xxxxxxxxxx Subject: NetBSD 3 SCSI broken Hello, After many months of testing things when I've had spare time, I can now say definitively that Quadra class machines (605, 650, 800) will eventually lock up under heavy SCSI usage.

Well, I do, but mine are all 1.6.x since I haven't seen the need to update. This makes me even less likely to. -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser@xxxxxxxxxxxx -- My Pink Floyd code: v1.2a s BO 1/0/pw tinG 0? 0 Relics 2 8 <6mar98> -------- Loading Comments...
