Re: MAGIC with HP KVM - someone will help?
Nop, sorry. I don't use KVMs. Perhaps the PS2 to USB converter is doing something bad. that was my first idea BUT: 1) i know for a friend that on some motherboards (it was embedded VIA based CPU) geli doesn't work at typing password. 2) in my case (as well as his case) problems happen everytime kernel function cngets is used, it maybe after being unable to mount root in a kernel prompt. The problem IS FreeBSD specific AND some hardware specific. this seems like an interaction between FreeBSD and some hardware (timings?).

Re: MAGIC with HP KVM - someone will help?
yes i have on of those that have PS/2 reset issues Unfortunately even good adaptors have their share of problems. as for now i already planned to rearrange boot sequence of this server and /etc/rc so network would be temporarily up and sshd active until i log in and geli attach needed devices. I refuse to move from the keyboard I have currently, and occasionally keys get 'stuck' but it's so obvious when it happens it's no big hardship. I have a Belkin adaptor one by the way, and it works but the PROBABLY FReeBSD specific is that some configuration, not only USB to PS/2 adapters, have problems only when kernel cngets routine. my friend switched to linux, in spite of lower performance, on his dedicated fileserver machine with VIA processor, only because keyboard didn't work when geli asked for password at boot, or - for whatever reason - in kernel command prompt activated. it works every other case properly.

This reminds me of a problem I have when using a RS-232 console. When the loader is sitting there waiting for a few seconds to see if you will type something, it doesn't always notice keystrokes. I would have to hold the key down (letting it autorepeat) and then it would usually notice. This problem does not happen with the PS/2 keyboard.

no ideas? On Wed, 20 Jun 2012, Wojciech Puchar wrote: i am not sure if it is related at all to FreeBSD, but maybe someone here know the solution. Anyway it is somewhat FreeBSD related for sure as you will see from description. I bought used IP 16 port KVM connected to few servers, in between them FreeBSD 8 server running on Dell PowerEdge T110. As this KVM have PS/2 connectors to keyboard and mouse i added USB to dual-PS/2 converter. So: 1)when KVM is used locally with plugged monitor, keyboard and mouse everything is fine. 2)when it is used remotely before FreeBSD is booted or after successful multiuser boot everything is fine. 3)when kernel boots and waits for GELI password, and i SLOOOWLY type it (at most one keypress per second) over remote KVM connection - everything is fine. 4)when i type the password faster keyboard locks. you have to turn off server and on again to recover. Please don't laught from 3 and 4 as it is true, tested several times. The problem happens ONLY at FreeBSD but before mounting root, when geli ask for password. And it is serious as ability to enter geli password is the main reason for this KVM to be installed! And really not forgetting to type password very slowly isn't easy. Any idea what it is and how to fix it. It really looks like magic. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
