Interestingly, I have now noticed the "mmap: Invalid argument" message when running this command: # rpm -i kernel-4.5.0-8.el7.aarch64.rpm I wonder if it is being produced in dracut, which is used to generate the initrd during the kernel installation. This may also be running in the anaconda case too. Could this be related to bug 1372200 ? It's quite likely that either Anaconda or Dracut are calling udevadm. Created attachment 1201776 [details]
strace output of failing process.
Same error message produce from "make zinstall" of kernel build.
It appears that /usr/sbin/lvm is producing the message.
In the attachment at line 406 we see the failure. and then subsequent error message being emitted to stderr
Moving to 7.5. Dear LVM team, This older bug report states that on some platforms, an mmap warning is seen during calls to the lvm binary while installing a kernel. It may or may not still be happening in 7.4, and is not critical. This bug requires more information. Jon. AFAIK - this was selinux bug which has been fixed long time ago. (mmap belong to selinux opened file right above mmap call) IMHO this bug could be safely closed as fixed already (and it's unrelated to lvm2 as lvm2 is not using mmap). All out of time for 7.4. Moving these bugs over to the Cavium 7.5 tracker for further work and review. --Chris Hey Zi, According to comment #7, >AFAIK - this was selinux bug which has been fixed long time ago. >(mmap belong to selinux opened file right above mmap call) > >IMHO this bug could be safely closed as fixed already (and it's unrelated to >lvm2 as lvm2 is not using mmap). Red Hat says this bug is fixed. Could you check to see if Cavium agrees? Thanks much. I just tested this on cav-thunderx2s-cn88xx-02.klab.eng.bos.redhat.com with RHEL-ALT-7.4-RC-1.0 and I did not see the "mmap: Invalid argument" message. https://beaker.engineering.redhat.com/recipes/4374183#installation I think we can close this bug.

Description of problem: System console is on a serial port, when anaconda is started from the installer, it reports: ------------------------- Starting installer, one moment... anaconda 21.48.22.86-1 for Red Hat Enterprise Linux 7.3 (pre-release) started. * installation log files are stored in /tmp during the installation * shell is available on TTY2 * when reporting a bug add logs from /tmp as separate text/plain attachments ================================================================================ ================================================================================ VNC Text mode provides a limited set of installation options. It does not offer custom partitioning for full control over the disk layout.

Version-Release number of selected component (if applicable): rhel-server-7.3-snapshot-2-aarch64-dvd.iso How reproducible: Everytime it seems. Steps to Reproduce: 1. PXE boot from the .iso files using serial console on Cavium CRB-2S system 2. Observe the message. 3. Actual results: mmap: Invalid argument Expected results: No mmap error messages Additional info: This seems new. I did not see it on rhel-server-7.3-beta-1-aarch64-dvd.iso
