Problem with HP Virtual Keyboard on DL320 on Dapper

[Henrik Riomar]

Binary package hint: linux-source-2.6.15

I have a problem with Dapper Server on a HP DL320 G4 server that seems to be related to the iLO module.

The following is seen in syslog (in an endless loop):

[42949735.860000] usb 5-2: new full speed USB device using uhci_hcd and address 22

After looking for solutions on the web it seems to be fixed in newer kernels and a patch is available (note: I have not verified this patch yet)

Hi Henrik,

I can confirm this bug. For Dapper and Edgy.
Did you see also the strange behaviour, when booting directly with an USB CDRom that the kernel from Dapper/Edgy is stopping after finding the PS/2 Keyboard Controller?

I can confirm this bug on a HP ProLiant ML310G4 with Ubuntu 6.06 LTS - it works with 6.10 (server).

Workaround:
When the installation hangs, switch to console 4 and unload the uhci usb module:

$ modprobe -r uhci_hcd

After that, the setup goes on. You'll have trouble again when booting into the installed system.
syslog and kern.log are getting bloated by the messages provided at the original bug report.
To avoid this, you have to unload the uhci module, make a new initrd and boot using the new initrd:

$ sudo rmmod uhci_hcd
$ sudo depmod -a
$ sudo mkinitramfs -o /boot/initrd.img-2.6.15-26-server-custom

modify the file "/boot/grub/menu.lst" and change the line 114:

initrd /boot/initrd.img-2.6.15-26-server
to
initrd /boot/initrd.img-2.6.15-26-server-custom

$ sudo grub-install hd0
$ sudo reboot

Note that this leads to a non-functional USB configuration. A patch to the Kernel has been done with 2.6.16.34 (vanilla).

Check that this patch isn't already in dapper kernel. If not, we'll pull it in.

[Matthew Palmer (mpalmer)]

This patch was added in 2.6.15-26.47, according to the current Dapper changelog. I'm just trying to work out how to easily create the new initrd and vmlinuz for the install CD, and I'll be testing this to see if the current version of the kernel (2.6.15-28.57) is OK.

[Martin Pitt (pitti)]

Right, so this should solve itself once we build new CDs.
