Tell me exactly what the hardware is (pciconf). Just wanted to let you know that after putting DDB/KDB into the kernel, the problem vanished mysteriously and I can not provoke the problem any more. I have traversed the changes since the build date to 09/18/2010 (when I built the new kernel) but have no clue what exactly fixed the problem. I have placed pciconf -lv, devinfo -rv, dmesg.boot and acpidump -dt information as well as sysctl dev.em output on the system just in case you will be interested in them: https://neptune.delphij.net/acpi/ Cheers, - -- Xin LI <delphij@delphij.net> http://www.delphij.net/ FreeBSD - The Power to Serve!
