The machine itself is an HP BL25p with 8 GB of RAM (but hw.physmem set to under 4G, it seems the isp driver needs this) and dual Opterons. Running amd64 code. This is what I get after issuing scsi_target -A -S -T -W 32 2:0:0 /data/file1 lock order reversal: (sleepable after non-sleepable) 1st 0xffffffff808ce680 targ global (targ global) @ /usr/src/sys/cam/scsi/scsi_target.c:418 2nd 0xffffffff808e98c0 kernel environment (kernel environment) @ /usr/src/sys/kern/subr_hints.c:117 KDB: stack backtrace: witness_checkorder() at witness_checkorder+0x4f9 _sx_slock() at _sx_slock+0x4d res_find() at res_find+0x41a resource_find() at resource_find+0x7e resource_find_dev() at resource_find_dev+0x5f cam_periph_alloc() at cam_periph_alloc+0x1df targioctl() at targioctl+0x3a7 giant_ioctl() at giant_ioctl+0x65 devfs_ioctl_f() at devfs_ioctl_f+0x6f ioctl() at ioctl+0x147 syscall() at syscall+0x517 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (54, FreeBSD ELF64, ioctl), rip = 0x800909aac, rsp = 0x7fffffffbb98, rbp = 0x7fffffffe700 --- Thanks, -- Attila Nagy e-mail: Attila.Nagy@fsn.hu Free Software Network (FSN.HU) phone: +3630 306 6758 http://www.fsn.hu/
