I had a quick look through the code and it seems you need to specify
soft-update-ness if you want to also specify newfs'ing or not.

eg try..
mlxd00s1-5=ufs /virtual 1 N

See line 1378 of label.c in src/release/sysinstall.

Hope that helps :)

LINT CPU features table

[Lucky Green]

[This inquiry found no takers on -questions, so I am trying it on
-hackers]

I found the list of CPU options in LINT to be not very accessible. What
would be considerably more useful, perhaps in addition to the
information in LINT, would be a table of CPU's, with a checkbox for 
each CPU feature that should/could be enabled for this particular CPU.

Is anybody here aware of such a table? If not, is anybody here able to
perhaps create such a table and add it to the Handbook? I believe it
would be of substantial help to the user.

"OK, I have an AMD K6-333". [User looks down the "AMD K6" row of the
table]. "I can turn on feature L, M, and Y".

Thanks in advance,

Automounting samba shares / pam_mount

[Lukas Ertl]

Hi -hackers,

I'm currently trying to find out how to automount homedirs via samba when
users log in (via ssh, ftp, telnet,...), and I've found pam_mount, a PAM
module which seems to do the trick under Linux. I've also found that this
module was rejected as a port about one year ago because the code was "too
messy", whatever that means :-)

Although I'm just a beginner in C, and these are my first steps in
"PAM-land", I tried to play with it and see if I can get it to work. Well,
I can't. I can compile it (with a few modifications), but if I add it to
pam.conf and try to login I get "unable to resolve symbol:
pam_am_authenticate" and similar errors in /var/log/messages. I'm not
quite sure how to solve this, so I hope I can get some advice from you.

Or would you rather say that I should forget pam_mount and look for some
other way to automount my samba shares (maybe even write a PAM from
scratch for this purpose)?

regards,
le

Getting PXE to leave an existing partition alone

[Jason Noble]

I've got a hundred systems that I'm looking at upgrading to 4.4 from
4.1.  These systems were originally setup with pxe, with the following
partioning scheme (install.cfg format):


# Now set the parameters for the partition editor on mlxd0
disk=mlxd0
partition=exclusive
bootManager=standard
diskPartitionEditor



# All sizes are expressed in 512 byte blocks!
#
mlxd0s1-1=ufs 40 /
mlxd0s1-2=swap 4096000 none
mlxd0s1-3=ufs 40 /var
mlxd0s1-4=ufs 8192000 /usr
mlxd0s1-5=ufs 0 /virtual
# Let's do it!
diskLabelEditor

For the upgrade, I'd like to leave the /virtual partition alone (it
contains user's home directories and such).  According to the
sysinstall(8) manpage I should be able to add a N to the end of the
/virtual partition line and it will not newfs the drive.  The following
line does not work (i.e. all the data on /virtual goes bye bye):

mlxd0s1-5=ufs 0 /virtual N

Has anyone used pxe to upgrade a system and leave one or more existing
FreeBSD partitions alone?  How should I go about this?

Thanks for any help you can provide.

mount_cd9660 is supposed to, out-of-hand, mount the last data track
on a CD, Worked for me as such on older, other boxes.

Well, I had tried that earlier on my box, but let me perform that
in front of an audience:

  # dmesg | grep acd0
  acd0: DVD-ROM  at ata1-master using WDMA2

  # sysctl -a | grep hw.ata
  hw.ata.ata_dma: 1
  hw.ata.wc: 1
  hw.ata.tags: 0
  hw.ata.atapi_dma: 1
  hw.atamodes: dma,dma,dma,---,

  # cdcontrol -f /dev/acd0c Info | grep data
 11  54:12.68   7:08.38  243818   31988   data

  # mount_cd9660 -s 243818  /dev/acd0c /mnt
  mount_cd9660: /dev/acd0c: Invalid argument

I've tried this with both DMA and PIO on my drive, which I'll point
out is a DVD-ROM drive, not a CD-ROM drive.

With your pointers, though, I was able to correctly use 'mount'
using both of my test CDs on another box running 4.1-RELEASE with
a classic CD-ROM drive:

  acd0: CDROM  at ata0-slave using UDMA33

So, this issue at hand is some combination of my kernel (4.5-RELEASE)
and my hardware (DVD-ROM).  Any further suggestions?

What _exactly_ do you mean? I can't get your logic(?) in the above sentence.

There is no workaround. I've been studying both implementations for the last 
two weeks. I actually implemented a partition viewer based on the linux 
kernel code which works under linux, but is confused in the same way as the 
freebsd kernel is, when run under freebsd. I think you haven't read my 
initial posting with full attention...

This is actually the default for my system.

I'm not seeing any stray interrupts, either:

I am a tad suspicious of sharing interrupts with the SB Live card, though.
I'm going to next disable the onboard IDE (thought I had already done that,
sigh) and the parallel port to get a few irqs back and try to arrange for
the sound card to use one of them.

Most likely, it's the SCSI card IRQ determination that's taking
a long time to run, when the IRQ is shared.  Basically, if you
get an interrupt, all the devices that are attached to it have
to be polled to see if they caused it.

For some reason, polling the SCSI controller appears to be taking
a relatively very long time (or actually having work to do, with
nothing connected to it).

This could be indicative of a bug in the driver for that card,
since the poll routine should decide that there is nothing to
service for the card, and just return very, very quickly.

It could also be indicative of a problem with the hardware,
where the SCSI card is generating interrupts when it's bus is
unterminated or simply "because it feels like it" (this should
not happen, in practice; you can use "vmstat -i" to see if it
is happening anyway).

I don't know if it's safe/prudent for the OS to disable two
stage controllers (like SCSI or ATA) that aren't going to be
useful to the system without a target present.  If it's possible
to hook up a device to the bus, and not have to inform the
system for the device to become recognized (e.g., it should be
possible to not require an explicit user initiated reprobe, at
least for SCSI, if there is a SCSI reset when an unpowered target
is powered, so this would end up needing to be sysctl'able), then
it should be possible to avoid the extra bus overhead associated
with a poll, automatically.  I would *strongly* discourage anyone
from implementing this optimization until the underlying SCSI
problem is diagnosed and fixed, since from your report, it would
be very effective in masking the problem without fixing it, until
someone hooked up a disk or tape, and things went to hell again.

Well if tools blow up on multiple platforms, I'm inclined to point to a
corrupt partition table.  Linux may have a workaround but it doesn't get
around the root brokenness.

Fix your partition table and your systems will be happy.

If you have NNTP enabled, you might try disabling that, as well.  It
could be something unexpected in the timer code.

Another alternative could be to force:

kern.timecounter.method: 0
kern.timecounter.hardware: i8254

If this is not the default on your system, in case it's a coupling
problem.

I get the "repeating last sample" also (good way to describe it).

This may be unrelated, but I also found out that the sound driver isn't 
happy when the card shares its IRQ with someone. The Dell Precision has 
an onboard SCSI controller that by default shares an IRQ with the sound 
card. Even with no SCSI disks connected, the sound would be really 
choppy. When I disabled the SCSI controller in the BIOS, those problems 
went away.

Nope.  Well, sometimes, but not often.  When I am, I get the "repeating
the last sample" effect during the freeze, the same as if the sound card
wasn't generating interrupts (or the system wasn't servicing those
interrupts).  This is one of the things that makes me suspect interrupt
problems.

I've seen these, too, on a dual-P3 Dell Precision 420. Under high loads 
(buildworld), I get the exact same short-time freezes that sometimes 
recover, and sometimes lockup the machine solid.

We have the same sound card (and network card), and in my case, not 
playing audio during high loads solves the problem - are you using your 
audio device at all when this happens?

Re: Numerous hard hangs on TWO different ASUS P4T-E w/P4 1.6G

[Frank Mayhar]

I'm experiencing hangs as well.  At first I thought it was the fxp0/sym
driver thing, but I've since changed hardware almost completely and the
hangs persis.  I'm now strongly suspecting some kind of interrupt problem.
For the record, I've attached my dmesg output.  This is a dual AMD MP 1900+
(1.6 GHz) Tyan 2466N-4M system.  3Com xl0 ethernet, Adaptec 39160 and 3940
SCSI, Creative Soundblaster Live! audio, Radeon 8500 128MB video (XFree86
4.2).  2GB DDR memory.

I see very common short-term hangs, a few seconds to less than a minute.
The mouse and keyboard stop responding, X stops updating and everything
just pauses, the whole system (including the network).  It then starts
back up, often dropping keyboard or mouse data.  Once in a while (not
sure how often, but at least every couple of days) it hangs solid and
never comes back.  Totally unresponsive.  This invariably requires a
hard reset.

This is a busy system.  Near-constant load on the network (some 40-100KB/s),
lots of disk accesses.  Seems worse when network and/or SCSI load is high.

Dmesg output follows.  If there's anything I can do to help diagnose this
problem, please let me know...

AMI Megaraid + Reboot problems

[Byron Schlemmer]

Hi folks I have sent the following to freebsd-questions but maybe this
is  a better place to ask?

I have a AMI MegaRaid controller :

amr0:  mem 0x-0x irq 11 at device 11.0 on pci0
amr0:  Firmware E161, BIOS 3.13, 32MB RAM

running on :

$ uname -a
FreeBSD machine 4.6-RC FreeBSD 4.6-RC #0: Tue May 28 15:35:17 BST 2002
root@machine:/usr/src/sys/compile/EHSB  i386

Now the problem is whenever I reboot, or shutdown, the box seems to
shutdown correctly, then I get a message saying :

amr0 flushing cache ... done
Rebooting...

And the machine seems to hang there, never actually rebooting? Has
anyone else experienced this? Any solutions to actually get the box
to reboot?

The value you give to this sysctl is not a boolean, it's a value used in
the formula which computes the randompid.  This value is sanity checked,
that's why giving 1 doesn't do anything.  Here is the code which is
responsible for this :

if (pid < 0 || pid > PID_MAX - 100) /* out of range */
pid = PID_MAX - 100;
else if (pid < 2)   /* NOP */
pid = 0;
else if (pid < 100) /* Make it reasonable */
pid = 100;

This should give you enough information to chose a good value. :-)

That's the wrong file I gave you, that should be this file:

/home/repositories/freebsddiary/phpPgAds/ChangeLog,v

Once I fixed the releases file to point to the correct repo (DOH!), both 
tags worked (. and FreshPorts2).  That should have been my clue.   The 
collection exists in both repos but with different tags (and different 
customizations for each website).

Thank you John.  :)

But this will be one of those transparent features, correct?

It appears that most of these are features that are 'use as needed.'  In
other words, if I don't need them, I don't need to know about them.  On
the other hand, when moving to 4.0 there were issues with hardware
(specifically PC-cards and sound) that gave me a hard time for quite a
while.  These were less about new features and more about underlying
architecture and stability, and getting new code to work correctly.

Other than devfs (which I haven't investigated yet) it seems most of
these features are extras, not the basics, correct?  Other than SMP, of
course.
