Hardware is a 256mb HP Netserver LPr with an HP network card (it's an Intel chipset, fxp driver). SCSI is 895 using ncr0 on this box. I have been running a number of similar boxes in various functions for some time with little trouble. Today I was greeted with a trap 12. Unfortunately no single swap device has enough space to hold a crash dump as they are interleaved. The kernel is recompiled with maxusers 256 and unnecessary drivers disabled, so the instruction pointer is of limited interest. It is given below. In case the offset relative to the start of add_rfabuf helps: 23:49> ~:maia# nm /kernel|grep ^c01b6[7-b]|sort c01b67a4 t fxp_mediachange c01b67d4 t fxp_mediastatus c01b6910 t fxp_add_rfabuf c01b6b30 t fxp_mdi_read c01b6b9c t fxp_mdi_write Apologies for the truncated additional information, the box had to be reinstated quickly, so my notes were rather hurried: ip 08:c01b69e0 base 0x0 lint ffff type 1b sp 10:c0257988 dpl 0 pres 1 def32 1 gran 1 fp 10:c0257998 int ena, res, iopl=0 ints net/tty/bio/cam The Ethernet driver reports the device as being the following: fxp0: rev 0x05 int a irq 11 on pci1.3.0 Bearing in mind my experience in debugging is rather limited, please let me know if I can supply any additional information or do anything should this recur that would help to trace the source of the panic.
