Description Valdis Kletnieks 2007-08-29 17:08:19 UTC 
Description of problem:
After installing glibc 2.6.90-13, the system time as reported by gettimeofday()
started misbehaving - the first 5 minutes of uptime it would be correct, but
after the 5-minute jiffies rollover, the time reported by 'date' and other
programs would jump ahead 4096 seconds.  'uptime' would still report the right
time, and 'touch foo; ls -l foo' would show correctly as well.  When booting
with 'vdso=0' things work properly. (This also affected xscreensaver, see bug
#258281)

Version-Release number of selected component (if applicable):
glibc-2.6.90-13

Additional info:
Unclear if this is a glibc issue, or a borked vdso in the -mm kernel.
