Subject: 64bit kernel not booting with CONFIG_PRINTK_TIME=y

Hi all,

I've been trying several times to boot a 64bit kernel with
CONFIG_PRINTK_TIME=y and each time it failed.

This is the output of my L2000 when trying to do so :

Information: No console specified on kernel command line. This is
normal. PALO will choose the console currently used by firmware
(serial). Command line for kernel: 'root=/dev/md1 console=ttyS0
palo_kernel=2/vmlinux' Selected kernel: /vmlinux from partition 2
ELF64 executable
Entry 00100000 first 00100000 n 2
Segment 0 load 00100000 size 4997120 mediaptr 0x1000
Segment 1 load 00634000 size 640576 mediaptr 0x4c5000
Branching to kernel entry point 0x00100000.  If this is the last
message you see, you may need to switch your console.  This is
a common symptom -- search the FAQ and mailing list at parisc-linux.org

Recompiling with CONFIG_PRINTK_TIME=n makes it works straight away.

How can this be troubleshooted ? Any idea what the problem could be ?

I'm using gcc-4.2.4 with kernel 2.6.26 but I've have had very same
results with gcc-4.1.2 and 2.6.25.

Cheers,
  Guy
