Re: Inspiron 9400 freezes when enabling bfe0
:I just got me a brand new Dell Inspiron 9400 Notebook, Intel Dual

:rsp. console freezes with ACPI enabled.
:Not a big deal, though, booting without ACPI enabled does the trick,
:but what really bothers me: when I try to" ifconfig UP" the internal

:The same holds true after starting dhclient; in fact, any attempt to
:UP bfe0 causes a freeze.

:everything freezes as soon as the network card gets involved (tried

:Anyway, if this is not a known issue, I can provide any dump files

:P.S. I tried the whole common variety of things-to-try, like disabling

Hmm. We don't have polling support in that driver or I'd suggest
trying to run it in polling mode.
Try an SMP build without APIC_IO.
Have you tried the FreeBSD livecd to see if FreeBSD can operate the
This might require some significant debugging to figure out. A
complete freeze is either an interrupt storm (which is unlikely
since we have code to detect storms), or a code loop in the driver,
or a bus deadlock or bus fatal error due to improper programming of
the device. Sprinkling a bunch of kprintf()'s in the device code
paths might help narrow down the issue, and comparing the driver
against the driver in FreeBSD might yield fixes or other issues
that we need to apply.
