During the preparation for testing the recent changes made to the SUN4D specific code in the kernel by Sam Ravnborg the following was discovered: Since the removal of of_platform_bus_type (commit: eca3930163ba8884060ce9d9ff5ef0d9b7c7b00f ) multiboard SUN4Ds have not been able to boot. The kernel crashes due to a zero-pointer error encountered when registering multiple M48T59 RTCs (There is one on each board). A patch for the was previously submitted, but the problem was not as serious at that time (would only generate warnings). Now the kernel will crash and stop executing before the serial console has been started. (Crash output can be viewed by using the -p boot flag) Signed-off-by: Kjetil Oftedal <oftedal@gmail.com> --- arch/sparc/kernel/time_32.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
