Sorry bout that WHSE. Here's my info
$this->bbcode_second_pass_code('', '[root@Arch Linux ARM install ~]# pacman -Q udev
udev 171-1
[root@Arch Linux ARM install ~]# uname -a
Linux Arch Linux ARM install 2.6.31.6_SMP_820 #101 SMP Tue Apr 12 20:34:36 UTC 2011 armv6l ARMv6-compatible processor rev 5 (v6l) Oxsemi NAS GNU/Linux')
Currently syslog-ng is off and udevd was rebooted, running constant 7-9%cpu

ALSO I had to shutoff hd-idle as it kept crashing my plug when it tried to sleep the USB HDD. Not sure what's causing it or if it is related to this issue, but it never did it before.

udev bumped to 171-2 today, does that help at all?

$this->bbcode_second_pass_quote('kmihelich', 'u')dev bumped to 171-2 today, does that help at all?

[ohthanks]

been having the same issues on a new pink plug I bought during the buy.com sale.

updating to 171-2 didn't seem to resolve anything for me. Commenting out $this->bbcode_second_pass_code('', '/sbin/udevadm settle --quiet --timeout=${UDEV_TIMEOUT:-30}') from rc.sysitit allows it to boot without any of the logging issues, so it does seem to be related to the settle command.

I'm unable to get it to boot with any usb drives attached though, just a flashing green until I pull the drives out and restart it. Then no problems. Plugging them back in with udevd running is fine and it detects/mounts them with no trouble. I assumed this was related to udevd being weird, but I'm not really sure now, any suggestions would be appreciated.

I have a dockstar which I always leave updates lagging, so comparing rc.sysinit (old one date 3rd April) produced a staggering amount of changes, but that entry was-
/sbin/udevadm settle

Here is my old rc.sysinit

This mornings udev update on my PogoPlug Pro did not help. When I ran the update, this is what updated:
$this->bbcode_second_pass_code('', '[2011-06-10 07:44] Running 'pacman -Su'

')

After that I still have the same issue. And now my hostname isn't being set, "[root@(none) etc]". I did edit the /etc/rc.sysinit, to comment out the udev settle command, then later removed the comment.. so not sure if that is the cause...

Also on another thread it mentions how to get the kernel .config file. I do not seem to have the /proc/config.gz file... not sure if this is a symptom, or something unrelated.

Running a system update on my PogoPlug V2 Pink.... Hostname is not set (same as PogoPlug Pro), but udevd is not running out of control. Also it does have the /proc/config.gz file.

[WarheadsSE]

/proc/config.gz is a compile-time option for the kernel, which was not set at the time I compiled the running kernel for the OXNAS boards.

For what it's worth, I have found that it's possible to boot up a Debian 2.6.32-5-versatile kernel using qemu-system-arm along with the root filesystem from ALARM-2011.06-oxnas-rootfs.tar.gz with the same modifications as done by oxnas-install.sh and additions from pack.oxnas.kernel.modules.tar.gz ... After a first-time boot with various module errors, I made a symbolic link in /lib/modules/ from 2.6.32-5-versatile to 2.6.31.6_SMP_820 and did a "depmod." Then after a reboot, everything went well, except (1) there was no eth0, (2) "s0" was respawning fast (easily fixed by commenting it out in /etc/inittab), and (3) the very same "udev" issue arose as described in this thread (taking up all CPU cycles until I killed it). There is no udev issue while using the native Debian root filesystem.

I mention all this as another possible tool to help diagnose the udev problem further. Naturally, I am tempted to see what might happen if I substitute the Debian "Versatile" root filesystem as /dev/sda1 on the Pogo Pro, while using the newly flashed 2.6.31.6_SMP_820 kernel. I imagine I might still have problems with eth0 and other devices, but just maybe the udev problem would go away. I must admit I still haven't quite had the nerve to install the Arch Linux ARM software directly onto my Pogo Pro, although I have successfully added and tested an eSATA connector with an external 2.5" drive powered by USB.

[WarheadsSE]

directly as in installing the rootfs into the NAND?

Hell no, dont.
