Rolando Zappacosta, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Description changed: I'm consistently not able to boot from an HP EliteBook 6930p on-board card reader; same SD card boots OK when inserted into an external USB card reader plugged to the PC. This happens for both Ubuntu 11.04 and 10.10. Steps taken: 1) Created a bootable installation SD card by means of "Create a USB startup disk" on another PC running Ubuntu 2) Plugged that SD card into the on-board PC's card reader and: - A) got the: - "/init: line 7: can't open /dev/sr0: No medium found" - and: - "Unable to find a medium containing a live file system" - messages - B) got an initramfs prompt - C) plugged in another USB device (SAMSUNG_SGH-i900) and then captured into it the output of the following commands: - ls -l /dev/disk/by-path => file: ls-l_dev_disk_by-path.txt - ls -l /dev/disk/by-id => file: ls-l_dev_disk_by-id.txt - ls -l /dev => file: ls-l_dev.txt - dmesg => file: dmesg.txt - and copied the files: - - casper.log => file: casper.log - - casper.vars => this file was empty + A) got the: + "/init: line 7: can't open /dev/sr0: No medium found" + and: + "Unable to find a medium containing a live file system" + messages + B) got an initramfs prompt + C) plugged in another USB device (SAMSUNG_SGH-i900) and then captured into it the output of the following commands: + ls -l /dev/disk/by-path => file: ls-l_dev_disk_by-path.txt + ls -l /dev/disk/by-id => file: ls-l_dev_disk_by-id.txt + ls -l /dev => file: ls-l_dev.txt + dmesg => file: dmesg.txt + and copied the files: + - casper.log => file: casper.log + - casper.vars => this file was empty 3) Inserted the same SD card into the external USB card reader and plugged it into the PC; booted fine. From its shell: - A) captured to the file "BootFromUSB.txt" the output of these commands: - lspci - lspci -v - lspci -vv - lspci -t - lsusb - lsusb -tv - lshw - uname -a - dmesg + A) captured to the file "BootFromUSB.txt" the output of these commands: + lspci + lspci -v + lspci -vv + lspci -t + lsusb + lsusb -tv + lshw + uname -a + dmesg - May be the problem comes from having the booting process and the kernel referencing the on-board card reader device/partition differently? - Any kernel parameter worth trying? - Anything worth debugging? - - TIA, - Rolando. + WORKAROUND: I had to append the option "LIVEMEDIA=/dev/mmcblk0p1" to the + kernel parameters in order to boot successfuly from the USB pendrive. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/810484 Title: USB boot from PCI card reader fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/810484/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
