Hi Chaps I am tracking 6-STABLE, FreeBSD funkalicious.home.dom 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #8: Thu Feb 23 23:24:57 GMT 2006 root@funkalicious.home.dom:/usr/obj/usr/src/sys/funkalicious i386 I have a fairly straight-forward kernel config (see below) I think, yet if I enable "device atapicam", and buildkernel and installkernel and reboot, the system starts up fine until it get's to finding disks and then it goes incredibly slowly, takes about 5 minutes to get to "harvesting interupts" and so on and so on, I think it will eventually get to the login prompt, but I havent been tolerant to wait that long >15 minutes. Are there known problems with atapicam? or conditions under which it causes a massive system slow down, some sort of conflict timeout or loop problem maybe? My System is - Intel Pentium IV 3.2GHz MSI 848P-Neo Motherboard 2GB DDR RAM (2x1GB) 1 x 120GB Maxtor SATA Hard Disk HighPoint Tech RocketRaid 1640 RAID5 Card (with 3 x 250GB Maxtor SATA Hard Disks attached) NVIDIA GeForce 6800LE 256MB I have tried booting the system with and without the HighPoint RAID Driver (hpt374.ko = http://www.highpoint-tech.com/USA/bios_rr1640.htm) loaded and it seems to make no difference. If I dont use "device atapicam" the system is perfect, but I could really do with enabling it, for CD/DVD writting purposes... Thanks Adam. ############# Kernel config ############# makeoptions COPTFLAGS="-O2 -pipe -funroll-loops -ffast-math" machine i386 cpu I686_CPU ident funkalicious options SCHED_4BSD # 4BSD scheduler #options SCHED_ULE # ULE scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories 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 COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_FREEBSD5 # Compatible with FreeBSD5 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 ADAPTIVE_GIANT # Giant mutex is adaptive. device apic # I/O APIC # Bus support. device eisa device pci # Floppy drives device fdc # ATA and ATAPI devices device ata device atadisk # ATA disk drives device ataraid # ATA RAID drives device atapicd # ATAPI CDROM drives options ATA_STATIC_ID # Static device numbering # ATAPI -> SCSI Interface, mainly for cdrecord #device atapicam # causes boot problems?!?
