I found another "manual" workaround for this problem, which works also on a HP t5735. When booting Ubuntu 9.04/i386 you get dropped to the initram shell since it cannot find the USB device. Plugging out and re- plugging in the USB device makes it magically appear, therefore typing "exit" at the initram shell prompt continues normal booting and succeeds. After installing Debian 5.02 on the same machine the USB boot problems are gone. I haven't tried earlier Ubuntu versions though.
I have similiar problems on completely different machines: On a very old 266MHz ThinTune thin client, when running Ubuntu 9.04 Server, the machine first boots the kernel fine off an internal CF card and is then supposed to continue booting userland and friends from USB. The last step fails though - unless you (unplug and re-)plug in the USB device after getting dropped to the initram shell. The same happens for a "UD2" thin client from Igel (http://www.igel.de/igel/live.php,navigation_id,3561,_psmand,1.html) which is equipped with a VIA chipset, CPU etc. To me it seems that the USB boot problems mentioned here are *NOT* related to the ATI RS600/690 chipset, but affect a lot of other machines as well. I attached the lspci output of the thintune machine. I suggest, we should change the topic to reflect the generality of the problem. ** Attachment added: "thintune_lspci.txt" http://launchpadlibrarian.net/29968383/thintune_lspci.txt -- Jaunty does not boot from USB on SB600/RS690 https://bugs.launchpad.net/bugs/350531 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
