'insmod uhci' crashed GRUB2

[Dennis Heinson]

Binary package hint: grub2

I am using the current karmic alpha. I have a USB keyboard, which does not work in GRUB2 by default. So i tried dropping to a console in GRUB and typed (with a regular keyboard)

insmod uhci

I didn't get further than that. It crashed. Thanks for looking into this!

(GRUB2-Version=1.97beta3)

Afaik, the USB support in Grub2 is broken. I exeperienced similar issues with a HP nc8430 and ended up using a USB stack taken from another project. The only convenient way I found to use a USB keyboard in Grub2 is having a BIOS that can handle it.

No it's not in general broken.
It's just very young and not well tested on real hardware.
AFAIK it was mainly coded with the usb support from qemu.

Ok, "broken" isn't the good word, "untested" fits better. It crashed
with most of the computer I tested it on (this means 3 or 4 machines).

After reading the code, it seemed pretty complete for real hardware, but
I'm not an UHCI expert myself. ;)

Hmm, so if I have USB keyboard I have no chance to use GRUB menu with current [karmic] release of ubuntu? It seems holding shift while booting allowed me to enter into the menu, but no other functionality is provided to be able to use my keyboard, and I have no PS/2 keyboard. I think it's a serious issue if something goes wrong and I would need to use grub menu (eg boot rescue) which is not possible if you have decent hardware even without PS/2 connectors :( Also the "insmod" stuff is not useful if you cannot connect a PS/2 kbd at all ...

same bug affects me when trying to boot from sdhc card, i asked on irc #grub and a developer told me that it's fixed in newer grub versions (relative to 1.97~beta4-1ubuntu4.1 that i'm using now), so it would be good if the ubuntu package maintainers upgrade from upstream, please...

They already did. But the updated package is only in lucid not karmic.

I'm trying to boot with a USB Keyboard. Unfortunately, I can't enable Legacy USB support in my BIOS (MB: Asus P4C800 Deluxe) because then I'm unable to boot with my external USB hard drive attached. I'm running Lucid. After chatting some folks on the #grub irc channel, I was advised to try the instructions here:

http://grub.enbug.org/USBSupport

While I can run "insmod uhci" when dropping to the grub command line, my machine crashes running "insmod usb_keyboard". Synaptic says current version of grub-pc is 1.98-1ubuntu8. If there's a way I can contribute via testing, please let me know. Thanks.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
