Hi, I have a new supermicro X6DH8-G server with an Adaptec 2200S RAID controller. 2200S firmware build 7349. I booted and installed FreeBSD from the 5.2.1 CD image. System was fine. I did cvsup to 5.3-STABLE & installed new kernel and world. When I restarted it would display: Waiting 15 seconds for SCSI devices to settle aacd0: <RAID 0/1> on aac0 aacd0: 139948MB (286614016 sectors) and than hang for about 45 seconds. Then I would get a continual message: AAC0 command 0xc31c3bb8 TIMEOUT AFTER X Seconds (the command changes through a small group of values) forever. The same thing happens with the 5.3 Kernel from the MINI ISO cdrom. I was able to determine that it is related to the APIC interrupt by trying safe mode and device hints. If I include the /boot/device.hints = hint.apic.0.disabled="1" the kernel I built boots and seems to work fine. I stress tested by doing several of simultaneous compiles. The 5.2 kernel is still installed as /kernel.orig. It shows a dmesg line for the controller as: aac0: <Adaptec SCSI RAID 2200S> mem 0xdc000000-0xdfffffff irq 72 at device 2.0 on pci3 aac0: [MPSAFE] aac0: Unknown processor 100MHz, 48MB cache memory, optional battery not installed aac0: Kernel 4.2-0, Build 7349, S/N be8f06 aac0: Supported Options=31d7e<CLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,WINDOW4GB,SOFTERR,SGMAP64,ALARM,NONDASD> aacp0: <SCSI Passthrough Bus> on aac0 aacp1: <SCSI Passthrough Bus> on aac0 The 5.3 kernel I built and boot with the above hint returns: aac0: <Adaptec SCSI RAID 2200S> mem 0xdc000000-0xdfffffff irq 5 at device 2.0 on pci3 aac0: can't set up FAST interrupt aac0: Unknown processor 100MHz, 48MB cache memory, optional battery not installed aac0: Kernel 4.2-0, Build 7349, S/N be8f06 aac0: Supported Options=31d7e<CLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,WINDOW4GB,SOFTERR,SGMAP64,ALARM,NONDASD> aacp0: <SCSI Passthrough Bus> on aac0 aacp1: <SCSI Passthrough Bus> on aac0 My questions: 1. Is there any reason not to run with hint.apic.0.disabled="1"? Any disadvatages to the smaller number of IRQs? I do not have many devices, no usb/onboard scsi. Only need ide cdrom occasionally. 2. Wher should I report this for fixing? 3. Are there any other suggestions / recommendations? thank you -- Mike Selner
