Rebooting will not normally cause the problem, only actually powering down, and it is somewhat hardware dependant. (If your terminal acts as an open circuit when unpowered, it will not cause this problem.) Some sparc models can be set to ignore break on the serial console. (This may also depend on openboot version.) -- Blars Blarson [EMAIL PROTECTED] http://www.blars.org/blars.html With Microsoft, failure is not an option. It is a standard feature.
Re: Problem with "Happy Meal" drivers
I am reasonably certain this doesn't happen on (some?) sparc hardware. I've had an Ultra30 plugged into our E450 via serial, and when I rebooted it, I don't recall finding the E450 at PROM later. I could be wrong, of course.

A break signal on the sun serial port drops it into the openboot prompt. 'go' restarts it where it left off. In rs232 a break is signaled by holding the line low for longer than 10 bit times (therefore it cannot be a valid byte b/c a valid byte would have ended with a high stop bit at the 9th bit[1]). Some PCs inadvertently drive TX low for that long as power goes down. There isn't much you can do; I even tried lowering the baud rate and even as 1200 the PC's signal was long enough to act as a break. -Nicolas Dade [1] assuming 8N1; the principal is the same with other data settings--- a break is unambiguously not a data transfer

Re: Problem with "Happy Meal" drivers
Before you turn off the PC that is connected to the Sun's serial console, remove the cable from the sun. That way, the sun will stay running and you won't have these problems. a On Sun, Jan 11, 2004 at 02:38:26AM +0100, bath66 wrote: > Hello, > > I'm using a Sun Ultra (sparc64) which is running under the kernel > 2.4.24-SMP.

Problem with "Happy Meal" drivers
Hello, I'm using a Sun Ultra (sparc64) which is running under the kernel 2.4.24-SMP. I also use two network cards handled by your driver (sunhme) : A SunSwift (eth1) which is connected to my LAN and the onboard card (eth0) which is connected to the internet thru PPPoE. Im using this machine as a small gateway. Unfortunately, i've got a very annoying problem : when all the computers of the network are switched off - the gateway remaining the only active computer on the LAN - it is irremediably crashing. So I switch on one PC, connect to the console port (the network isn't working anymore) and then type 'return', i get into the PROM and type 'go' and get this message : eth1: Happy Meal out of receive descriptors, packet dropped. I type 'return' again and the computer doesn't react anymore, I can't even access the PROM. Further more, when I reboot, this message doesn't appears in the logs. By the way, between the last computer's switch off and the reboot of the gateway, nothing at all appears in the logs, which comfort me in the idea that the computer has totally crashed. Moreover, switching the network cards has no effects - the result is the same when the Sunswift is connected to the LAN, which leads my suspicions to the driver. My network is composed of a 8 ports switch 100mbps which connects a PC, a laptop and the sparc. I tried to apply the patch which adds "udelay(1)" to the line 1983 (found at http://sparclinux.net/pub/patches/U1-hme-lockup.patch) but it doesn't change anything and the problem stays the same.
