SMP hang at boot on Compaq Proliant ML370
Hello. On a brand new Compaq Proliant ML370, I installed FreeBSD 5.0RC2, without any problems. It works very well when using only one CPU. To take advantage of the two available CPUs, I compiled a new kernel with the two necessary SMP options, installed it, then restarted the server, but it hangs when booting the new kernel, just after the following line has been displayed : APIC_IO: testing 8254 interrupt delivery. Reading some archives tells me this message appears just before the others CPUs are started, so I suppose this is the problem. The server is configured for Unixware7, as told in the archives. Has anybody an idea ? Thanks. -- Nicolas To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

I just tried this option, and the server still hangs at the same point. Any idea ?

I tried this. Now there is only the ahc driver (the only one needed) compiled in the kernel but this does not help, the server still hangs. I also removed the ata driver, without success. :-( Any other idea ? Thanks. -- Nicolas To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

I received it last Friday. I think these rumors are true...:-( -- Nicolas To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

If this can help, I have put the boot log file for Linux 2.4.18 with SMP enabled at this URL : http://www-verimag.imag.fr/~kowalski/rochail.log Maybe can I help for other things ? -- Nicolas To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Additionnal tests show that a Linux client running am-utils (6.0.7) also hangs (same error message) when trying to mount shares from a FreeBSD 5.0R server.
