With this patch, kernel boot messages get prefixed with a timestamp
counting from the boot, although in fact early messages (before kernel
command line parsing) don't get timestamped.
The output looks something like this:
[ 0.003999] Calibrating delay loop (skipped) preset value.. 5866.95 BogoMIPS (lpj=2933478)
[ 0.007546] Security Framework initialized
[ 0.009056] SELinux: Disabled at boot.
[ 0.012702] Dentry cache hash table entries: 65536 (order: 7, 524288 bytes)
[ 0.016942] Inode-cache hash table entries: 32768 (order: 6, 262144 bytes)
[ 0.020233] Mount-cache hash table entries: 256
Of course you only see this when the verbose flag is set.
Rich.
