What went wrong? that's ok - i've got some local qa helpers that have config options. Things like making SMP bootups more likely in randconfig, adding various boot parameters to the bootup via .config methods (so that boot parameters can be randomized via make randconfig), etc. these: CONFIG_BOOTPARAM_SUPPORT=y CONFIG_BOOTPARAM_NO_HZ_OFF=y CONFIG_BOOTPARAM_NMI_WATCHDOG_BIT_0=y CONFIG_BOOTPARAM_LAPIC=y CONFIG_BOOTPARAM_IDLE_MWAIT=y CONFIG_BOOTPARAM_NOPAT=y CONFIG_BOOTPARAM_NOTSC=y are equivalent to adding this to the boot line: nohz=off nmi_watchdog=1 lapic idle=mwait nopat notsc although i dont think they are normally material to netconsole workings.
