System: NetBSD Mandylion 2.0_BETA NetBSD 2.0_BETA (Mandylion) #9: Wed Apr 28 01:46:14 CEST 2004 juan@Mandylion:/home/juan/httpd/nbsd/obj/sys/arch/i386/compile/Mandylion i386
I was trying to play with the MPACPI and MPACPI_SCANPCI options
in the kernel on my UP Athlon. So I built a new kernel
with MULTIPROCESSOR, COM_MPLOCK, ioapic*, and ehci(4), uhci(4),
You can see my kernel config here:
When booting the new kernel, all was fine before starting the
ehci(4) driver, the machine rebooted instantly.
I tried commenting out ehci(4) from the kernel configuration, and
all works as expected. Probably the same happens in 2.0_BETA, I
tried that in -current (2.0E).
The ehci controller in question:
VIA Technologies VT8237 EHCI USB Controller
Please let me know if you need some more information about the
hardware or something like that.
Build a kernel with MULTIPROCESSOR, MPACPI, MPACPI_SCANPCI, and
I wish to know why...
