During the boot process at least 125MHz, 250MHz and 550MHz cannot be locked. I uploaded a full serial dump from the n900 with debug output from omap2_dpll_round_rate to the following url: http://paste.debian.net/24628/ -- Sebastian signature.asc Description: Digital signature

I guess omap2_dpll_round_rate() for some reason thinks that with the given sys clock its not possible to lock the DPLL at 125Mhz. If you can send the debug logs from omap2_dpll_round_rate() that should probably help know whats going wrong. > > -- Sebastian > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
RX51: kernel message spam from CPUfreq driver
Hi, On RX-51 (Nokia N900) the (mainline) kernel constantly outputs the following message about 2-3x per second since some releases: [ 1038.314514] cpu cpu0: CPUfreq: Cannot find matching frequency for 12500 (The message is from drivers/cpufreq/omap-cpufreq.c, line 100) This is really annoying and makes debug output without a "grep -v" basically useless. Can you give me some hints how to solve the problem? -- Sebastian signature.asc Description: Digital signature
