dma_alloc_coherent issue with tg3 in x86_64 build
During boot of dom0, I get the following. Box is remote, so I''m
now waiting for proxy power button pusher ;-) tg3 init fails doing
dma_alloc_coherent (I assume this is from tg3_init_one -> tg3_test_dma ->
pci_alloc_consistent -> dma_alloc_coherent). Looks like an issue with
the amount of memory in dom0. Is this known?
thanks,

Monotonicity correlation coefficients
Could anyone help me to find the mathematical expression to calculate the monotonicity correlation coefficient between two variables?
Thanks in advance.

Domain Crash and Xend can''t restart
I have a single VM (of 11) that has a recurring problem. This image has
moved from machine to machine, with the problem following it. This image
has been rebuilt from scratch, and the problem recurred. It would appear
that there is something in the behaviour of this VM which causes it to crash
and causes Xend to become unhappy.
The problem presents as:
Domain crashes, becomes zombie.

Regressions with monotonicity constraints
This seems to be a recurrent topic, but I don't remember hearing a
definitive answer. I also apologies for cross-posting.
Say I have a numerical response variable and a bunch of multi-level factors
I want to use for modeling. I don't expect factor interaction to be
important so there will be no interactions in the model.
All this would be a perfect job for ANOVA except for one additional

Using local disk for cache on an iSCSI zvol...
I''m just wondering if anyone has tried this, and what the performance
has been like.
Scenario:
I''ve got a bunch of v20z machines, with 2 disks. One has the OS on it,
and the other is free. As these are disposable client machines, I''m not
going to mirror the OS disk.
I have a disk server with a striped mirror zpool, carved into a bunch of

Uneven CPU speed with CentOS 4.4 on a Mac Pro
Hi list,
I've recently managed to install CentOS 4.4 on an Apple Mac Pro.
Functionality-wise everything works great, but when trying to benchmark
the system, I don't get stable runtimes, they differ by more than 30%.
For example a benchmark run with our PDE solving code takes between 500
and 800 s on the completely unloaded machine.
Suspicious kernel output (complete output attached):

patterns of missing data: determining monotonicity
Here is a problem that perhaps someone out here has an idea about. It
vaguely reminds me of something
I've seen before, but can't place. Can anyone help?
For multiple imputation, there are simpler methods available if the
patterns of missing data are 'monotone' ---
if Vj is missing then all variables Vk, k>j are also missing, vs. more
complex methods required when the

X86_64 and 4GB RAM using Flat Memory Model?
Hello,
I have an odd problem on a dual processor, dual core Opteron system.
Obviosously it is x86_64 so should have no problem with large amounts of
RAM. The system has 4 GB installed (2GB on each processor).
If I boot the system with a fresh install of Debian Etch it sees all the memory
fine. dmesg reports:
Memory: 4107008k/5242880k available (1929k kernel code, 86836k

[PATCH v2 00/11] x86: xen cpuid() cleanup
Reduce special casing of xen_cpuid() by using cpu capabilities instead
of faked cpuid nodes.
This cleanup enables us remove the hypervisor specific set_cpu_features
callback as the same effect can be reached via
setup_[clear|force]_cpu_cap().
Removing the rest faked nodes from xen_cpuid() requires some more work
as the remaining cases (mwait leafs and extended topology info) have
to be handled

reading time value in dom0 and domU kernels
Hi Folks,
I want to calculate latency in transferring a buffer from domU kernel to
dom0 kernel and vice versa. for that I need a time ''flavour'' (cycle counter
time?) which reads the same in dom0 and domU. Could someone please let me
know if cycle counter time is the right time to use? if not then which one
(system time or wall clock time)? Also could someone please tell me how to

Xen and QNX
I am trying to get QNX working with Xen. I''ve going about it in a
similar way as installing windows with Xen, but when I start the guest
up to install the OS it hangs on the line:
''Hit Esc for .altboot.......''
If anyone has managed to get this working, or has any ideas/advice for
me here it would be greatly appreciated!

Xen 3.3.1 Windows HVM Disk I/O -> domU and dom0 hangs
Hi,
we are currently working on getting windows working on your xen servers.
but we are facing a severe problem where dom0 and all domus hang for
1-5 seconds from time to time.
we think it is probably because of disk i/o, because top sometimes
says 100% wa (waiting on io) during the hang.
dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7.
should we give dom0 more than once

3.0.4 ACPI support and Opteron 2210 ?
Hello,
I originally posted this to xen-users, but someone suggested I post it here.
I am having ACPI problems on a PenguinComputing Altus1600 system.
It has 2x dual core Opteron 2210 processors.
The system boots with a standard Debian or Ubuntu SMP kernel, with ACPI
enabled. However the xen live cd, binary xen install, as well as my own custom
compile of xen 3.0.4 from source will not boot.

I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs.
However, I need more RAM -- but cannot remember if all (four) RAM

or if there are two slots left to use.
However, I'd like (and think that it's possible, but don't remember how)

OpenIPMI on a SunFire v20z
Hi all,
New to the list and (mostly) new to CentOS. We have just moved from
running RHEL to CentOS on our main production servers.
Anyway, I am configuring a couple of new SunFire v20z servers here at
the moment and trying to get the systems' management interfaces to work
fully under CentOS.
First issue was trying to install the openipmi RPM from the CD that came
with the SunFires, this RPM
