It's not possible for the DC21140 status register to be all 1s. There is something seriously broken here. > May 9 18:51:04 daily-planet /kernel: de0: abnormal interrupt: 0xfcefa044 [0x1a040] > May 9 18:51:04 daily-planet /kernel: de0: abnormal interrupt: 0xfceea004 [0x0a000] This is bad. Very bad. Very very very very bad. Abnormal interrupt + Fatal Bus Error, type Master Abort. >From the DC21140 bible: Fatal Bus Error -- Indicates a fatal bus error ocurrred. If a system error occurs, the 21140 disables all bus access. 5.5.2.1.3 Master Abort If the target does not asert _devsel_l_ within five cycles from the assertion of _frame_l_, the 21140 performs a normal completion. It then releases the bus and asserts both master abort (CFCS<29>) and fatal bus error (CSR5<13>). I have never ever seen this happen. This is basically either the TritonII host-bridge is screwing up big time or some other device is screwing up the PCI bus. Didn't intel recently (as of week weeks ago) introduce a new rev of the TritonII chipset(s)? What does FreeBSD think your machine has in it? I would worry about your motherboard and not the SMC 10/100. -- Matt Thomas Internet: matt@3am-software.com 3am Software Foundry WWW URL: http://www.3am-software.com/bio/matt.html Westford, MA Disclaimer: I disavow all knowledge of this message
