Apologies in advance for not having a better troubleshooting approach. I'm at a loss... I maintain a large number of CentOS 7 based machines that utilize pam_mount to service (CIFS) user homedirs. This has worked swimmingly for many years. I recently rebooted a test node into both kernels 4.18.0 and 4.18.1 to find that upon user login (the triggering of pam_mount of CIFS homedir -- eg, local users/homedirs do not trip the problem), the kernel spontaneously reboots :/ Roll back to 4.17.4 and all is well again. Further strang-ifying things, is that static CIFS mounts (via /etc/fstab) _do_ mount as expected in 4.18.x. functional state: $ cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core) $ uname -r 4.17.14-1.el7.elrepo.x86_64 $ rpm -qa |grep pam_mount pam_mount-2.16-5.el7.x86_64 $ grep "$(whoami)" /proc/mounts //dfs.ad.domain/path/to/USER /home/ad.domain/USER cifs rw,relatime,vers=2.0,sec=krb5i,cache=strict,username=user,domain=ad.domain,uid=MYUID,forceuid,gid=MYGID,forcegid,addr=dfs.target.ip,file_mode=0700,dir_mode=0700,soft,nounix,serverino,mapposix,rsize=65536,wsize=65536,echo_interval=60,actimeo=1 0 0 Given that the static mounts (which use ntlmsspi) work fine (in 4.18.x) i, I thought I'd return the user homes back to ntlmsspi; but the spontaneous reboot is still triggered. Any ideas how I might better troubleshoot this? Or is this possibly pam_mount somehow tickling the newer kernels in a bad way? Thanks in advance
