While taking the Xorg 7.2 upgrade plunge on my newly installed ULE driven box. I got the following panic. panic: _mtx_lock_sleep: recursed on non-recursive mutex ahc_lock@/usr/src/sys/dev/aic7xxx/aic7xxx_osm.h:203 cpuid = 0 Uptime: 12s panic: _mtx_lock_sleep: recursed on non-recursive mutex ahc_lock@/usr/src/sys/cam/cam_periph.h:182 At this point, the keyboard was locked up so getting a backtrace wasn't possible. The relevant lines from dmesg are ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xb800-0xb8ff mem 0xfeafe000-0xfeafefff irq 16 at device 4.0 on pci3 ahc0: [ITHREAD] aic7880: Ultra Single Channel A, SCSI Id=7, 16/253 SCBs sa0 at ahc0 bus 0 target 5 lun 0 sa0: <DEC DLT2000 8B37> Removable Sequential Access SCSI-2 device sa0: 5.000MB/s transfers (5.000MHz, offset 15) da0 at ahc0 bus 0 target 0 lun 0 da0: <SEAGATE ST39216N 0010> Fixed Direct Access SCSI-3 device da0: 10.000MB/s transfers (10.000MHz, offset 15) da0: Command Queueing Enabled da0: 8761MB (17942584 512 byte sectors: 255H 63S/T 1116C) -- Steve
