elilo option to disable perfmon
Hi,
Is there any option to disable perfmon from elilo? I ask this question because when I boot my tiger4 at loading ramdisk, it begins to infinite loop with message,
perfmon: Spurious PMU overflow interrupt on CPU1: pmc0=0x0 owner 00000000000000
perfmon: Spurious PMU overflow interrupt on CPU2: pmc0=0x0 owner 00000000000000
I used UL IPF version kernel 2.4.20.
(please cc me when replying the mail)
Thanks,

No there is no such an option. Perfmon is a kernel compile time option.

This should not happen at boot time.
I don't know what is in UL (United Linux?)?
Could you try with a more recent kernel 2.4.21 from Bjorn?

I remember seeing this kind of error when playing with usingPAL_HALT_LIGHT in the cpu_idle loop. Newer PAL solved the problem. If you have CONFIG_IA64_PAL_IDLE turned on in your config file, you either need to upgrade to new firmware (not sure what rev to recommend on a tiger box) or disable the config option and rebuild a kernel. Try for PAL 7.40 or better. Thanks,
Alex

Latest BIOS for Tiger is S870BN4A.86B.0898.P07.0305300848 which includes PAL 7.59
