I am getting reproducible panics by pressing almost any key while system is booting or is in shutdown. Once it is up -- it works mostly fine. Also I noted that the keyboard was not working on my laptop while in the booting phase -- so after I managed to get a second panic doing fsck, I was unable to do anything in single-user mode. The only working keys I found were ScrollLock/Pause and Ctrl-Alt-Del :) Howewer rebooting it with acpi turned off I managed to get it working. The overall impression is that something is wrong with syscons, so it causes system panics when key is pressed and nobody listens to the terminal. I am trying to check if this issue is present in RELENG_5_4, and could also try to get crash dump if somebody is interested in digging it. BTW, did somebody else had problems with ehci? I had a problems with processes trying to read/write msdos/ext2fs partitions from usb2 drive getting stuck in wdrain (if I didn't mispell it) state. However I am not absolutely sure here, and want to do some more testing. I suspect that the usb2ide bridge I have is somewhat too cheap and buggy, as I also saw similar kind of problems with windows (the lamp on the drive constantly lights, and after some time windows disconnects it), but freebsd seemed to trigger this problem very efficiently. -- Best regards, Alexander.
