From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.0.0-10; Linux) Description of problem: In /proc/uptime, the fractional part of uptime is always .00, and the idle time is bogus. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. awk '/cpu/{print $1, $2 + $3 + $4 + $5, $5}' /proc/stat 2. cat /proc/uptime Actual Results: cpu 12993221 12411794 cpu0 12993221 12411794 129932.00 21.124147 Expected Results: cpu 12993221 12411794 cpu0 12993221 12411794 129932.21 124117.94 (approximately) Additional info: This happens because at line 141 in fs/proc/proc_misc.c, a 64-bit parameter (uptime64 >> 9) to sprintf() is interpreted as a 32-bit one ("%lu"). Either casting the shift result to unsigned long, or changing the format to "%llu" will solve the problem.
