But I consistently see upstream git: Always produces this oops on reboot checkout of 38d47c1b: Always produces this oops on reboot checkout of 94aca1da (one patch before the above commit): Reboots fine without the oops. This is petty specific to the particular userspace, looks like. I only see this on SLES10 installation. Also, I need a non-root user logged in at least once after boot through X to see this problem. I was always seeing this as I had autologin on local terminal and was remotely rebooting the system. If I just boot to init 3 or boot to init 5 with no user logged in or boot to init 5 with root logged in, I do not see this problem.
