Hi, after update to 3.8, every update of the kernel ends up in an unbootable machine. It is due to the following commit: commit 68d929862e29a8b52a7f2f2f86a0600423b093cd Author: Matthew Garrett <matthew.garrett@xxxxxxxxxx> Date: Sat Mar 2 19:40:17 2013 -0500 efi: be more paranoid about available space when creating variables efibootmgr which tries to add an entry and silently fails when writing to /sys/firmware/efi/vars/new_var with -ENOSPC. There are many entries in there: # efibootmgr BootCurrent: 000D Timeout: 0 seconds BootOrder: 0018,0000,0001,0002,0003,0007,0008,0009,000A,000B,000C,000D,000E,000F,0010,0011,0012 Boot0000 Setup Boot0001 Boot Menu Boot0002 Diagnostic Splash Screen Boot0003 Lenovo Diagnostics Boot0004 Startup Interrupt Menu Boot0005 ME Configuration Menu Boot0006 Rescue and Recovery Boot0007* USB CD Boot0008* USB FDD Boot0009* ATAPI CD0 Boot000A* ATA HDD0 Boot000B* ATA HDD1 Boot000C* ATA HDD2 Boot000D* USB HDD Boot000E* PCI LAN Boot000F* ATAPI CD1 Boot0010 Other CD Boot0011* ATA HDD3 Boot0012 Other HDD Boot0013* IDER BOOT CDROM Boot0014* IDER BOOT Floppy Boot0015* ATA HDD Boot0016* ATAPI CD: Boot0017* PCI LAN Boot0018* Linux Remaining size is about 20k, added entry size is hundreds bytes, store size is 64k. Obviously lowering the limitation from 1/2 to 1/4 fixes the problem for me because it always worked on my setup to store a new entry... Any ideas how to overcome that? It would be better to blacklist bad machines rather than whitelist good ones, right? thanks, -- js suse labs -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
