Kernel upgrade problem

[symbiat]

I recently used software updates to upgrade from the 2139 to the 2157 kernel, but the new kernel does not appear in the list of kernels at the boot prompt.

/boot and yaboot.conf look OK:
# ls -al /boot

Probably the software update missed an important step? So how can I boot the newest kernel and make it appear as the default in the bootloader? This is a G3 B&W PPC machine with SCSI disks.

Probably best to just: yum update kernel (in a terminal as root). Reduces the chance that something was corrupted by updater.

Don't forget the "_FC5"

/sbin/mkinitrd /boot/initrd-2.6.17-1.2174_FC5.img 2.6.17-1.2174_FC5

:-)

[symbiat]

If you recall from the earlier listings, I already have an initrd, so not surprisingly I get this:
# /sbin/mkinitrd /boot/initrd-2.6.17-1.2174_FC5.img 2.6.17-1.2174_FC5
/boot/initrd-2.6.17-1.2174_FC5.img already exists.

I suggest you rename your existing initrd file to something else - maybe append a .old to it. Mkinitrd will then produce a new file for you.

You could add a -f flag to the mkinitrd call to force it to overwrite the existing file but I wouldn't recommend it!

Please, only run:

ybin

that's all

Symbiat, post: #6 Thanks.

I noticed that selinux policy (in enforcing mode) doesn't allow yaboot to update kernel files
I opened a bugzilla https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=206789
