I have seen the watchdog and reset problem on a -STABLE laptop, both em and iwi. It only occur when I try to connect using Mulberry e-mail client so I thought it could be a problem with the linuxilator. The load on the box is normally low but both driver have shared interrupts, either with cbb or usb. Here is what I can see: uname -a: FreeBSD viglaf 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #55: Thu Sep 21 22:15:38 CEST 2006 root@viglaf:/usr/obj/usr/src/sys/VIGLAF i386 dmesg: em0: <Intel(R) PRO/1000 Network Connection Version - 6.1.4> port 0x8000-0x803f mem 0xc0220000-0xc023ffff,0xc0200000-0xc020ffff irq 11 at device 1.0 on pci2 em0: Ethernet address: 00:0d:60:89:36:e8 em0: [FAST] iwi0: <Intel(R) PRO/Wireless 2915ABG> mem 0xc0214000-0xc0214fff irq 9 at device 2.0 on pci2 iwi0: Ethernet address: 00:16:6f:8b:0a:21 vmstat -i interrupt total rate irq0: clk 11148090 999 irq1: atkbd0 32271 2 irq5: pcm0 atapci+ 157115 14 irq6: fdc0 1 0 irq7: 1 0 stray irq7 1 0 irq8: rtc 1426745 127 irq9: cbb1 cbb2++* 26582 2 irq11: cbb0 em0++* 762544 68 irq12: psm0 516858 46 irq14: ata0 43494 3 irq15: ata1 82 0 Total 14113784 1265 This is a development machine so I can debug and test patches as needed.
