did not add necessary "arp 1"

[Rajesh Pralhad Deo]

Ubuntu Dapper Drake release, boot script for "Loading Hardware Modules" (udev, S10udev) hangs while running /sbin/udevplug

Following text is outputed on the console, this text is not found in syslog

udevd-event[....]: wait_for_sysfs: failed to load ... '/sys/..../i8042/serio0/serio2/bus'

Pressing control-c kills the script and boots the system.

System is IBM Thinkpad R40 running 2.6.15-19-686.

There are other problems while the kernel boots,
1. PNP ACPI
[4294670.881000] pnp: PnP ACPI init
[4294670.883000] pnp: PnPACPI: unknown resource type 7
[4294670.883000] pnp: PnPACPI: METHOD_NAME__CRS failure for PNP0c01
[4294670.884000] pnp: PnPACPI: unknown resource type 7
[4294670.884000] pnp: PnPACPI: METHOD_NAME__CRS failure for PNP0c02
[4294670.884000] pnp: PnPACPI: unknown resource type 7

2. Several messages such as below
**** SET: Misaligned resource pointer: ceaf5d02 Type 07 Len 0

Not sure if these things are related.

Running /etc/init.d/udev restart causes a similar hang and eventually timeout, no message is reported in this case.

 Bug #34286 seems to be the same bug

[Scott James Remnant (Canonical) (canonical-scott)]

Rajesh, confirm that adding the "arp X" line fixed this for you (you commented to this affect on the other bug).

If so, when did you install this?

[Rajesh Pralhad Deo (rpdeo)]

Scott, the system was installed on Sun 19th and updated to 2.6.15-19-686 on 20th. Adding "arp X" selector to /etc/iftab fixes the boot delay. This also removes the wifi_ifrename directory in /sys/class/net and is listed as wifi0 now.

Also there is still PCI/PNP stuff in /dev/.udev/failed. I am guessing fixing ACPI PNP problem in the kernel will fix these issues.

[Scott James Remnant (Canonical) (canonical-scott)]

Ok, so it's a netcfg bug then; that should have written an /etc/iftab with the right details. Could you attach the /etc/iftab and note what changes you made to it.

Also could you attach "ifconfig -a" output

[Scott James Remnant (Canonical) (canonical-scott)]

I just had a sudden thought; what card was that that needed the arp 1? Was it plugged in and detected by the installer? Could you attach "lspci" and "lspci -n"

[Rajesh Pralhad Deo (rpdeo)]

The system was updated from breezy with 'apt-get dist-upgrade'
so it must have been netcfg from breezy. The card that needed arp 1 is
a Aironet wireless card (not pcmcia). Here is ifconfig -a and lspci
outputs.

Wireless connectivity is still broken, but I am guessing that is
because of the airo driver. I am using network-manager +
wpa_supplicant with a WEP network.

Here are the contents of /dev/.udev/failed:

I posted this via email, I hope you guys got the attachments as they don't show up on the web interface here.

[Scott James Remnant (Canonical) (canonical-scott)]

Ok; it would have been the netcfg from breezy then.

If you get a chance, try installing from Dapper Flight 6 instead -- that should generate the correct iftab file for you.
