Public bug reported: Binary package hint: linux-headers-2.6.35-22-powerpc64-smp
After upgrading from 10.04 to 10.10, IBM pSeries server is unable to boot and fails to initramfs.

Dropping to a shell! /dev/sda2 doesn't exist because the ipr module needed for IBM SCSI cards is missing, so kernel can't talk to the disk. /usr/src/linux-headers-2.6.35-22-powerpc64-smp/drivers/scsi$ ls ip* ls: cannot access ip*: No such file or directory .config file shows: # CONFIG_SCSI_IPR is not set A search revealed it's been turned off to avoid a compile issue. http://kernel.ubuntu.com/git?p=lag/ubuntu- maverick.git;a=commit;h=5c8ed50f14b1bce9b37178e4a4eaa8311468e177 UBUNTU: [Config] disable CONFIG_SCSI_IPR on powerpc Temporarily disable CONFIG_SCSI_IPR on powerpc to avoid build failures. Signed-off-by: Leann Ogasawara <[email protected]> Any IBM pSeries machine will be unable to boot with this disabled. There are likely very few pSeries machines running Ubuntu, but a fix would be nice for the few that are. Workaround is to boot the old kernel from 10.04 which still has the ipr module. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: kernel-scsi powerpc -- pSeries machines unable to boot Maverick - ipr module missing https://bugs.launchpad.net/bugs/662969 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
