           Summary: dist-upgrade from hoary to breezy caused pesky IRQ
                    problems
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: linux
        AssignedTo: ben.collins at ubuntu.com
        ReportedBy: era+ubuntu at iki.fi
         QAContact: kernel-bugs at lists.ubuntu.com

On 2005-10-24, I ran "sudo aptitude dist-upgrade" on a Hoary box which I had
installed as a "server" some weeks earlier from the regular i386 Hoary install CD.

The hardware is an IBM ThinkPad 600X. The only peripherals are two network
cards, one a very old Xircom PCMCIA one which has worked throughout all these
troubles, and in the other slot I have been trying various cards. See below.

When I did a "dist-upgrade", the CardBus wlan card -- a D-Link DWL-650+, Prism
chipset -- stopped working, and various other CardBus cards I tried would also
not work (Intel e100 and 3Com 3c59x). I finally managed to get at least the 3com
card to work with the "irqpoll" kernel boot option, and am reluctant to
experiment more at this point, as I don't have a replacement handy for this
particular part of my home network infrastructure. :-/

I had barely installed the following packages and done some minimal
configuration tweaks for them before the dist-upgrade.

ssh
ipmasq
dhcp
cvs
patch
linux-image-2.6.10-5-686 <- should probably have installed linux-686, but I'm
fairly new to Ubuntu
wireless-tools
hostap-utils
./hostap-modules-2.6.10-5-686_0.2.6-1+2.6.10-34.6_i386.deb <- compiled from
hostap-source on another Hoary box
hostapd
apache-perl
twiki <- purged immediately; could not get it to work sensibly
screen
sed -e 's/hoary/breezy/' /etc/apt/sources.list
sudo aptitude update && sudo aptitude dist-upgrade

I imagine the problems might have been there before, but after the dist-upgrade,
the wlan card stopped working, even before I rebooted. The dist-upgrade did not
actually install a new kernel, even though linux-image-2.6.12-9-386 is included
in the listing:

204 packages upgraded, 31 newly installed, 3 to remove and 0 not upgraded.

My primary suspect would be the hotplug upgrade, but there's obviously a lot of
other things which might have affected this.

After a lot of desperate tweaking, I managed to get at least some cards back up
and running by booting with "irqpoll". I don't think any of this matters, but
during the tweaking I also installed the following packages:

linux-686
hostap-modules-2.6.12-9-686_0.4.1-1_i386.deb <- again, compiled from
hostap-source on another Hoary box

and disabled hostap and dhcp (renamed scripts in /etc/init.d and ran
"update-rc.d remove").

I have a bunch of log files but uploading them all is probably overkill. During
troubleshooting, I tried booting with various cards present or absent, with the
cards in different slots, with different network cables, etc, and I'm afraid I
don't have a good correlation of which log messages correspond to which
experiments any longer anyway.

Scrolling back through the logs, I see various messages about IRQ 10 and 11 in
the log file already before the upgrade.

If I inserted the 3com card in the lower slot (I believe this is socket 1) and
did ifconfig eth0 172.16.0.1 up the machine would freeze hard under some
circumstances. With the card in the other socket, this was less fatal, but I
could not get the card to work; it would appear to ping, but not get through,
and then throw a "netdev watchdog" error after some time.

I'll attach kernel log messages from the bootup sequence from before and after
the upgrade. You should keep in mind that I've switched the wlan card to a 3com
ethernet card in the meantime, and obviously upgraded the kernel, and now
finally added the "irqpoll" boot argument.

I don't expect you can do much to help me at this point, but I hope that others
will at least be able to get something out of this bug report if they should
stumble into the same problem.
