NetBSD 2.0.2


 Hi all,

 I am considering to install the latest NetBSD 2 on my 3000. Is an upgrade
 from 1.6.x supported, and there any issues I should be aware of?

 Thanks.

I'm not sure it was fixed, but in NetBSD 2.0, there was a memory leak in 
the kernel - it would, over time, just consume more and more memory until 
the system panics. The speed depends on how much you do with your machine. 
It wouldn't be bad to test with a local machine to see if the problem 
could be pinpointed.

Yes, upgrading from 1.6 is supported, it was the previous major
release.  Upgrading from 1.5 (and possibly 1.4) shouldn't be a big
problem either.

The configuration files in /etc/ will probably have changed quite
a bit, see etcupdate(8) and be prepared to adjust some configurations
manually.

 Looks like I have to shelve that plan ... I tried a miniroot install on
 a seperate drive, and the installer dumped me straight into the kernel (?)
 debugger. Wasn't there at one time an installation method via install
 kernel and loadbsd?

"db>" ?

Please report what the "trace" command tells.

Installing NetBSD 2.0 on A1200 -> panic: MMU fault

Hi all,

I'm trying to install NetBSD 2.0 on my A1200 (KS3.0, Blizzard 1230/50
accelerator (50MHz 68030 with MMU), 64MB fast mem, 4.3GB HD). I
partitioned the drive as per the install notes, and succesfully copied
the miniroot filesystem to the swap partition. The miniroot filesystem
starts to boot ok, then I get the following:

...
root file system type: ext2fs
uvm_fault (0x2142b8,0x0,0,0x1) -> 0xe
trap type 8, code = 402076d, v=0
pid=1,lid=1,pc=000A71A0,ps=2004,sfc=1,dfc=1
<register contents>
<kernel stack>
panic: MMU fault 
stopped in pid 1.1 (init) at netbsd:cpu_Debugger+0x6: unlk a6

Does anyone have any idea what the problem might be? The MMU works
well enough to run VMM in AmigaOS, and Debian runs ok, so I kind of
assume it isn't actually indicative of a faulty MMU. BTW I'm
completely new to NetBSD, so any instructions in longhand if possible
please :).

This sounds very wrong. Can you please report _exactly_ what you typed
to boot, and how you partitioned the disk?

Thanks for replying. Sure - I initially went with the default boot
line "netbsd -ASn2", then I tried -AS and -A (if I read the notes
right I shouldn't need the -n2 option) with the same result.

I've taken screengrabs of the hard disk partition details to avoid the
risk of typos, five 7kb png images, at the url below.
http://homepage.ntlworld.com/channel0/screens/screens.htm

In case you can't get to that, hopefully this is all the relevant info in text:

Name	DosType		FS	Size	Automnt	Custom Boot Code
DH0     0x444f5303	FFS	100MB	yes	no
DH1     0x444f5303	FFS	1002MB	yes	no
root	0x4e425207 	Custom	128MB	yes	yes, 16 blocks
swap	0x4e425301	Custom	128MB	yes	yes, 16 blocks
var	0x4e425507	Custom	64MB	no	no
usr	0x4e425507	Custom	2701MB	no	no

I followed the install notes to the letter as far as creating the
partitions with HDToolBox, except for increasing the partition sizes,
as far as I can tell, but maybe I missed something. Cheers.

What does the trace command (at the db> prompt) show?
