Created attachment 456418 [details] kernel-config.txt I hit the following crash last night. Line 2189 of fs/exec.c is a BUG() call in the pax_report_refcount_overflow() function. This is an older x86 server that has been up for probably a month or so. It handles rsync backups and sees a lot of filesystem activity.

Old version, masked package, ain't nobody gonna look into it (for what it's worth, I haven't seen this crash since).
