Description Jan Stodola 2022-02-04 20:15:06 UTC

This bug was initially created as a copy of Bug #2050877


Description of problem:
The nvram kernel module is not included in install.img on ppc64le.
The bootlist command then prints errors during the installation (ignore the printf messages):

INFO:program:Running... bootlist -m normal -o /dev/mapper/mpatha1
INFO:program:/sbin/bootlist: line 277: printf: 0x: invalid hex number
INFO:program:/sbin/bootlist: line 277: printf: 0x: invalid hex number

INFO:program:/usr/sbin/nvram: ERROR: cannot open "/dev/misc/nvram": No such file or directory
INFO:program:Could not update bootlist!

In the lorax build log from compose RHEL-9.0.0-20220203.0 I can see that all except of a few modules are being removed:
...
template line 42: removekmod drivers/char --allbut virtio_console hw_random virtio-rng ipmi hmcdrv
...

Location and size of the kernel module on the installed system:
[root@ibm-p9z-20-lp14 ~]# ls -lh /lib/modules/5.14.0-52.el9.ppc64le/kernel/drivers/char/nvram.ko.xz
-rw-r--r--. 1 root root 3.7K Feb  1 12:58 /lib/modules/5.14.0-52.el9.ppc64le/kernel/drivers/char/nvram.ko.xz
[root@ibm-p9z-20-lp14 ~]#

Version-Release number of selected component (if applicable):
RHEL-9.0.0-20220203.0
lorax-34.9.11-1.el9
lorax-templates-rhel-9.0-32.el9

How reproducible:
always

Steps to Reproduce:
1. run "modprobe nvram" in the installation environment

Actual results:
The nvram kernel module is not loaded.

Expected results:
The module is loaded successfully.

Additional info:
This problem was originally noticed in bug 2017652.

Comment 1 Jan Stodola 2022-02-05 10:54:47 UTC

lorax-templates-rhel-9.0-33.el9 works as expected, the nvram kernel module is included in install.img and bootlist succeeds now:

INFO:program:Running... bootlist -m normal -o /dev/mapper/mpatha1
INFO:program:/sbin/bootlist: line 277: printf: 0x: invalid hex number
...
INFO:program:/sbin/bootlist: line 277: printf: 0x: invalid hex number
INFO:program:sda
DEBUG:program:Return code: 0

Comment 2 Jan Stodola 2022-02-07 16:51:55 UTC

Setting Verified:Tested based on comment 1.

Comment 5 Jan Stodola 2022-02-16 17:13:55 UTC

./usr/lib/modules/5.14.0-58.el9.ppc64le/kernel/drivers/char/nvram.ko.xz is present in install.img of compose RHEL-9.0.0-20220215.4.
lorax-templates-rhel-9.0-33.el9 is included in RHEL-9.0.0-20220215.4.

Moving to VERIFIED.
