What's Next
I read somewhere that the PCIe issue is indicative of some other
hardware (PCIe SSD; etc) not working correctly.
Also, the 4.10 kernel is not the kernel out of the box. In a
environment with 10 or more servers do you really want a custom kernel?
How do you maintain all of these custom kernels (i.e. is a different
kernel required for a HP Gen 8 server different than a HP Gen 9
server?)?

bin/55346: /bin/sh eats memory and CPU infinitely
Hi!
It seems /bin/sh in 4.8-STABLE has problem with SIGCHLD processing.
In short, it often fails to process it correctly, zombies float
around, jobs are not marked as finished in jobtab[] that fills memory
and takes much CPU to be processed.
Run this one-liner using /bin/sh and see hundreds of zombies:
#!/bin/sh
while :; do : & done
A kernel will halt this as soon as it reaches limits and

Zen arch in 5.0?
Will 5.0 have scheduler, reg alloc etc. bits for explicit
support of AMD's 1st gen Zen (Ryzen, Epyc) arch?
Is it safe to assume that the changes for Zen's 2nd gen
will land prior to the hardware release, once the 1st
gen is added? I think zen2 will arrive next year.

How Can I ...
I've got a WD My Passport Ultra 1TB (USB) plugged into my router and I

It is not the only reason, when ES guests gain debug register support
then #VC also needs to be IST, because #DB can be promoted into #VC
then, and as #DB is IST for a reason,

parallel PSOCK connection latency is greater on Linux?
I'm not sure the user would know ;). This is very system-specific issue just because the Linux network stack behaves so differently from other OSes (for purely historical reasons). That makes it hard to abstract as a "feature" for the R sockets that are supposed to be platform-independent. At least TCP_NODELAY is actually part of POSIX so it is on better footing, and disabling

How many network packets are generated with and without it? If there
are many small writes and thus setting TCP_NODELAY causes many small
packets to be sent, it might make more sense to set TCP_QUICKACK
instead.

Deep Replicable Bug With AMD Threadripper MultiCore
The following program is whittled down from a much larger program that
always works on Intel, and always works on AMD's threadripper with
lapply but not mclappy. With mclapply on AMD, all processes go into
"suspend" mode and the program then hangs. This bug is replicable on an
AMD Ryzen Threadripper 2950X 16-Core Processor (128GB RAM), running
latest ubuntu 18.04. The R version

Kernel 4.12 and nVidia Driver
I tried to move to the latest stable kernel (4.12) so I could take
advantage of my newest custom system (Intel Core I7 6-core; 64 GB RAM;
MSI nVidia graphics card; 2 - 120 GB SSD; 2 - 4TB WD Black) on a UEFI
Asrock mother board.
I've had the machine for 3-months but I couldn't get it to work until I
found out that the Nouveau driver was causing me all the 'hardware'
issues. I

I've installed CentOS 7 with the latest kernel from elrepo (4.11.8),

If AMD's new CPUs aren't 100% compatible with existing software w/o
needing special versions, AMD is shooting themselves in the foot.

AMD Ryzen and CentOS
I have a new system with an AMD Ryzen 1600 CPU and I'm trying to run
CentOS, so far without success. The only information I could find was
a post reporting that CentOS 7 would crash during installation on a
Ryzen system: https://www.centos.org/forums/viewtopic.php?t=61831 .
I tried updating to the latest elrepo "mainline stable" kernel,
version 4.11 (by booting from a live CD and

About I386 not fitting on one DVD
Just a thought
If the I386 (or i686, never could figure out why the name change)
disk doesn't quite fit on the DVD+, and needs a DVD-, this might put
some folks at an inconvenience.
I wonder if the difference between fitting and not fitting is small
enough, so that some amount of pruning might make it fit on the DVD+R
image. Some ways to prune could be:
a) Create two versions of the
