We have variously shutdown all USB in the bios, pulled the Raid daughter board, and still cant solve this storm. Currently looking for the SMB 'kill switch' .. And will also look into the SATA chips, but with not much hope (soldering iron anyone?) A point or two -- we get bge0 but not bge1 under FreeBSD, and FresBSD 4.11, 6.2 and 7.0 all exhibit the same problem. The box seems to work with knoppix, insofar as we DO get both NICs and dont seem to get the storm. This data (knoppix) is a bit flakey as it was late at night so we didnt look too hard after the NICs came up. mjt --------------------------------------------------------------- The information transmitted in this e-mail is for the exclusive use of the intended addressee and may contain confidential and/or privileged material.
