Your situation is almost same as mine. I have a dual Xion 500MHz machine (NEC Express 5800/120Rb-2) with RCC LE chipset, 7899 onboard SCSI controller and Mylex RAID controller. With 4.0-STABLE smp enabled kernel, it hangs up while booting, after the proble of SIO. I also tried current kernel, but the situation was same. This problems is reported in freebsd-smp. http://www.freebsd.org/cgi/getmsg.cgi?fetch=0+0+/usr/local/www/db/text/2000/freebsd-smp/20000220.freebsd-smp In the thread of mail, it is reported that there may be a problem in PnP probing in SMP kernel. I have asked Conrad, the poster of the above mail, about his current status, and he still has same problem. I have tried install RedHad Linux on my machine, and ... it works! I heard that they had a problem in supporting multiple APIC, and it was fixed recently. I would like to suggest smp-hackers to invetigate Linux's code. -- Osamu MIHARA // NEC Printers Division To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
