During normal boot GENERIC kernel hangs with the last message being ips0: resetting adapter, this may take up to 5 minutes Ctrl-Alt-Del doesn't work. Pressing power button doesn't work either, have to push it and wait for several seconds to switch the system off. With hint.apic.0.disabled=1 GENERIC seems to boot fine. It's also possible to boot FreeBSD/i386 when hyper-threading is enabled (4 logical CPUs) and kernel has SMP option (just tried default SMP kernel). With only 2 CPUs (HTT disabled) SMP kernel also hangs at the same point. FreeBSD/amd64 only boots with apic disabled. This is not specific for 6.0 as RELENG_6 and CURRENT also have this problem. Logs of verbose boots and results of acpidump available at http://rsu.ru/~os/ips/ I'm ready to provide any possible help needed to resolve this issue. I've posted a message to freebsd-scsi and Scott Long pointed that this sounds like an interrupt routing problem. http://docs.freebsd.org/cgi/getmsg.cgi?fetch=20652+0+archive/2006/freebsd-scsi/20060219.freebsd-scsi http://docs.freebsd.org/cgi/getmsg.cgi?fetch=23717+0+archive/2006/freebsd-scsi/20060219.freebsd-scsi
Responsible Changed From-To: freebsd-bugs->freebsd-i386 This sounds as though it might be i386-specific.
As I mentioned in the original report this also happens with amd64. Behaviour is slightly different: system boots only with hint.apic.0.disabled=1. SMP kernels don't boot when APIC is enabled no matter if HTT is on or off. -- Oleg Sharoiko. Software and Network Engineer Computer Center of Rostov State University.
