But even if it's finished lapic keeps generating 2000 interrupts/sec and consuming 25% CPU usage when the machine is doning nothing. Any hints what I could do? I have never seen lapic before, I just did a fresh 6-snapshot (june) install and upgraded to yesterdays -current. Please find attached my kernel conf, although this time I use ULE the sluggish "make clean" behaviour was also with 4.2BSD (but I haven't looked after the CPU usage) Thanks, -Harry --Boundary-00=_LTDqC6KPVCbN7CX Content-Type: text/plain; charset="us-ascii"; name="CALE" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="CALE" #2005/06/05 ######################################## ## Kernel for D815UFVW ## ######################################## ## DEBUGS! options KDB # Enable kernel debugger support. #options KDB_TRACE #options KDB_UNATTENDED options DDB # Support DDB. options GDB # Support remote GDB. options INVARIANTS # Enable calls of extra sanity checking options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS options WITNESS # Enable checks to detect deadlocks and cycles options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed options KTRACE # ktrace(1) support makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols machine i386 cpu I686_CPU options PQ_CACHESIZE=256 # color for 512k/16k cache ident CALE options SCHED_ULE # ULE scheduler #options SCHED_4BSD # 4BSD scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options FFS # Berkeley Fast Filesystem options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options SOFTUPDATES # Enable FFS soft updates support #options UFS_EXTATTR #options UFS_EXTATTR_AUTOSTART #options QUOTA #enable disk quotas #options SUIDDIR options MD_ROOT # MD is a potential root device options NFSCLIENT # Network Filesystem Client options NFSSERVER # Network Filesystem Server options NFS_ROOT # NFS usable as /, requires NFSCLIENT options UDF options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options GEOM_BDE options GEOM_GATE options GEOM_LABEL options GEOM_MIRROR options GEOM_STRIPE options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] #options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options AHC_REG_PRETTY_PRINT # Print register bitfields in debug # output.
