(I've copied fabient@ because r233628 appears to have been the last commit in this area). I've just updated a P4 test box from r232545 to r235127 and it now panics during boot: panic: [intel,202] incorrect npmc count 35 Looking at sys/dev/hwpmc/hmpmc_intel.c line 202, the expected npmc count is 19. When I look at the actual code in pmc_intel_initialize(): pmc_mdep_alloc() initialises pmd_npmc to zero and then increments it by SOFT_NPMCS (16) in pmc_soft_initialize(). pmc_tsc_initialize() then increments it by TSC_NPMCS (1) pmc_p4_initialize() then increments it by P4_NPMCS (18) This totals 35 (as per the panic message). Can someone explain the KASSERT() that expects 19 - it boils down to KASSERT(0+16+1+18 == 1+18, ...) I gather not many people are running -current on a P4. -- Peter Jeremy
