Hi there colleagues, atapci3: <nVidia nForce MCP55 SATA300 controller> port 0xbc00-0xbc07,0xb880-0xb883,0xb800-0xb807,0xb480-0xb483,0xb400-0xb40f mem 0xefcb3000-0xefcb3fff irq 23 at device 5.2 on pci0 atacontrol detach ata7 - insert ATA disk (ad14) atacontrol attach ata7 pinics with Fatal trap 12: page fault while in kernel mode (kgdb) bt #0 doadump () at pcpu.h:196 #1 0xc0533227

Hi. I experimented a bit with collecting entropy from the time it takes for device_attach() to run (in CPU cycles). It seems that those times have enough variation that we can use it for entropy harvesting. It happens even before root is mounted, so pretty early. On the machine I'm testing it, which has minimal kernel plus NIC driver I see 75 device_attach() calls. I'm being very careful

I'm trying to make devd run an stty command whenever a USB serial device is attached. Unfortunately, $device-name is ucom[0-9] and the device names are /dev/cuaU[0-9] - how do I get the correct name in the device action? I haven't found a way to extract the number by itself, so I'm stuck with specifying a separate rule for each number, like so: attach 100 { device-name
