Sometimes when I have my printer (Epson Stylus Color IIs) turned on during a boot up, I receive a kernel panic when ppbus is being probed. The error is something along the lines of "supervisor read, page not present." If there is anyway to capture the output of the panic short of writing it down, I am not familiar with the debugger. Aside from once or twice with a boot disk and once with an improper kernel for my hardware, this has been the only instance I have had with a FreeBSD kernel panicing. It doesn't even happen everytime I boot with the printer turned on, I think it has only happened twice. If anyone can provide me with pointers on how to recover the error message completely, I will certainly provide a copy of it the next time I see it happen. In the meantime, has anyone else seen this problem? My kernel config: device ppc0 at isa? port? net irq 7 controller ppbus0 device nlpt0 at ppbus? device ppi0 at ppbus? and my dmesg: ppc0 at 0x3bc irq 7 on isa ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode nlpt0: <generic printer> on ppbus 0 nlpt0: Interrupt-driven port ppi0: <generic parallel i/o> on ppbus 0 Note that this was with the printer turned off. :) -- Jonathan Fosburgh Geotechnician Snyder Oil Corporation Houston, TX Home Page: http://www.geocities.com/vienna/1498 Manager, FreeBSD Webring: http://www.geocities.com/vienna/1498/computer/freebsdring.html ICQ: 32742908 AIM: Namthorie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
