Again weird result: linux-futexh-place-kernel-types-behind-__kernel__.patch #bisect good # # # edac # edac-mpc85xx-add-p2020ds-support.patch #edac-mpc85xx-add-mpc83xx-support.patch: smp_processor_id() bug? edac-mpc85xx-add-mpc83xx-support.patch edac-fix-resource-size-calculation.patch edac-i3200-memory-controller-driver.patch edac-i3200-memory-controller-driver-fix-offset-of-reg-in-i3200_edac-module.patch # bisect bad I put printk_delay patches to the head of queue. test five times, same results. bash-3.1$ grep EDAC .config CONFIG_EDAC=y # CONFIG_EDAC_DEBUG is not set # CONFIG_EDAC_MM_EDAC is not set There's no difference between bad/good kernel indeed because the edac code is not compiled. hardware is dell e5400 distribution is slackware 12.2 BTW, there's lockdep warnings while umounting a reiserfs partition, but I think it is not relevant.
