Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi, In current as of today, /stand/sysinstall generates the following kernel panic when probing for devices... --- (typed manually from console) --- fatal trap 12: page fault while in kernel mode fault virtual addres = 0x26c80 fault code = supervisor read, page not present instruction pointer = 0x8:0xc017309e stack pointer = 0x10:0xc8782d04 frame pointer = 0x10:0xc8782d04 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gram 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 163 (sysinstall) interrupt mask = none trap number = 12 panic: page fault scsi part from dmesg: da0 at ahc0 bus 0 target 10 lun 0 da0: Fixed Direct Access SCSI-3 device da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da0: 8761MB (17942584 512 byte sectors: 255H 63S/T 1116C) WARNING: / was not properly dismounted (cd1:ahc0:0:5:0): got CAM status 0x4c (cd1:ahc0:0:5:0): fatal error, failed to attach to device (cd1:ahc0:0:5:0): lost device (cd1:ahc0:0:5:0): removing device entry cd0 at ahc0 bus 0 target 1 lun 0 cd0: Removable CD-ROM SCSI-2 device cd0: 10.000MB/s transfers (10.000MHz, offset 15) cd0: Attempt to query device size failed: NOT READY, Medium not present Notice the cd1: lines, its a CDR (HP 4020i) which is not recognized because SCSI_DELAY was too short in kernel config. When I raise it too 15000 instead of 150 the cd1 is recognized on startup. And the panic went away, thats not the problem. My question is: Is the device entry removed ok from the system like dmesg says, sysinstall seems to still find something there when probing, and crashes the system. The scsi controller is a ahc type (onboard Asus P2B-S). Regards, Ron. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
