Subject: stall during boot on x86-64.
Date: Tue, 13 Dec 2005 22:22:03 -0500 [thread overview]
Message-ID: <20051214032202.GA3429@redhat.com> (raw)
When I boot my EM64T, I get a slight noticable pause
really early on in boot. Booting with 'time'
shows an interesting artifact.
Kernel command line: ro root=/dev/VolGroup00/LogVol00 console=ttyS0,38400 console=tty0 time
kernel profiling enabled (shift: 1)
[ 0.000000] Initializing CPU#0

[ 0.000000] time.c: Detected 2793.081 MHz processor.

[ 28.506519] Inode-cache hash table entries: 65536 (order: 7, 524288 bytes)
[ 28.539543] Memory: 1014240k/1047080k available (2490k kernel code, 32456k reserved, 1664k data, 236k init)
Note the jump in the time value..
I'm not sure this is actually where the pause I see is, as the text
is buffered, but it's something I can't explain.
