Description Forgotten User 9WJQF5tTlz 2007-08-12 14:43:36 UTC

While testing beta1, decided to swap the bigsmp kernel for the default one.

after reboot, the boot menu entries were different. the menu.lst file modifications lost other entries I had there.

This laptop has SLED10, Windows and OpenSuse 10.3, after the kernel change, the SLED10 entry was lost and the extra kernel options "vga=0x317 resume=/dev/hda5 splash=silent showopts"

The other effect shown was a corrupted X server. The bottom of the screen had garbage shown.

After I restored the original bigsmp, the kernel options were still missing and the X server still showed garbage.

I restored the kernl options manually and rebooted. The X server is OK now.

Could you add menu.lst - and also the backup, please?

Yast generated menu.lst with lost entries and missing kernel parameters.

Notice that the default menu selection is 2, not 0 as it was originally. The first  kernel entry is missing the kernel parameters.

Repaired menu.lst

This one is the manually repaired menu.lst. I've set default to 0, and restored the kernel parameters. Added the entry of SLED10 and its fail safe mode.

Will take care.

Have the same on my laptop.

Comment 13 Marco Michna 2007-08-24 12:05:14 UTC

But the problem seems to be that there is no kernel installed at all.
And even if I try to switch back to the bigsmp - no kernel is installed.

Comment 14 Stefan Fent 2007-08-27 08:23:11 UTC

Bootloader behaves as expected, reassigning

Comment 16 Katarina Machalkova 2007-08-28 08:11:30 UTC

Another Kernel.ycp (probably) issue, might be FaTE #159006 related

Comment 17 Jiri Srain 2007-08-30 11:03:37 UTC

The only complete log comes from Marco (comment #9). According to this log:

Looks like some problem accessing the server with the repository. Marco, can you check it?

I just tested it here in our local environment, and the kernel switch succeeded.

Comment 20 Marco Michna 2007-08-30 14:15:59 UTC

Just installed from scratch and didn't had the problem this time.

If you want then I can try another installation and rip out the network cable.
IMHO it should not delete the kernel if there is no connection to the source.

Comment 21 Jiri Srain 2007-08-31 12:59:29 UTC

OK, since it works now, decreasing the severity.

The reason why the old kernel was removed is that YaST first deleted the old kernel and afterwards downloaded new one. The network connection is not the only thing that can break - the package may be missing on the media, its signature may be wrong, etc. It is not possible to download everything first and then start the transaction (since some users do not have enough free disk space).

Passing to Olaf to try to find a way to preserve the kernel parameters in case of kernel removal followed by kernel installation. However, this is definitly not a blocker.

No ressources assigned here right now, will address problem later

Comment 24 Joachim Plack 2008-03-20 04:13:59 UTC

reevaluate for SLE11

Comment 25 Joachim Plack 2008-07-15 11:22:13 UTC

assign to yast2-bootloader maintainer

Comment 26 Jozef Uhliarik 2008-07-27 19:59:57 UTC

there exist fate request #302245. it solves problem with lost args for kernel params.
