This rather sound like a hardware problem - a power consumption spike the battery can't provide anymore or something, but let's see ... > The problem has appeared when a new driver for ipw/iwi was introduced. > > A fresh CURRENT here.

Can you make sure you have a complete debugging kernel with WITNESS enabled? Setting debug.iwi could also reveal what's going on. Unfortunately it's only a sysctl, not a tuneable, so you'd have to change the default in sys/dev/iwi/if_iwi.c line 88 by hand and recompile your kernel/module. By the way, are you using iwi built in or as a module? Do you load it via loader.conf or on demand from rc.d/*? -- /"\ Best regards, | [EMAIL PROTECTED] \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | [EMAIL PROTECTED] / \ ASCII Ribbon Campaign | Against HTML Mail and News
