amd64 on SU9400

[Patrick Welche-4]

I can netboot NetBSD-current/i386 on a system with a SU9400 which according
to http://ark.intel.com/Product.aspx?id=36697 has a 64-bit instruction set,
but not NetBSD-current/amd64.

Despite having NFS, DIAGNOSTIC, DEBUG, LOCKDEBUG, DDB, DDB_ONPANIC=1 in the
kernel, after "Loading nfs" and the /|\ animation the laptop simply reboots.

Any ideas given that works with i386?

Cheers,

Patrick

What is the output of
        cpuctl identify 0
on NetBSD/i386?

Luckily I grabbed a copy earlier :-)

It works with a kernel compiled from today's source. Could

- Fix rare crashe in the intr_lapic_tlb_bcast() handler: save and setup
  %fs on i386, %gs on amd64 registers, before using them.  Otherwise, it
  might be invalid/garbage, eg. IPI can interrupt userspace.

- Explicitly initialize per-CPU emap generation number.

Thanks <drochner> for reporting and testing of patch.


this have fixed it?!

hello,

i set up a box with netbsd 5.0 amd64. there are no X-components installed,
therefore the files /etc/rc.d/xdm and /etc/rc.d/xfs are missing. so security
checks from /etc/daily always claim:

Checking special files and directories.
missing: ./etc/rc.d/xdm
missing: ./etc/rc.d/xfs


because of this part from man security.conf(5):

The following mtree(8) tags modify how files are determined from
/etc/mtree/special and /etc/mtree/special.local:
     exclude  The entry is ignored; no backups are made
              and the differences are not displayed.
              This includes dynamic or binary files such
              as /var/run/utmp.

     nodiff   The entry is backed up but the differences
              are not displayed because the contents of
              the file are sensitive.  This includes
              files such as /etc/master.passwd.

i tried to block the check of those files by adding the following two lines
to /etc/mtree/special.local:

./etc/rc.d/xdm type=file mode=0555 tags=exclude
./etc/rc.d/xfs type=file mode=0555 tags=exclude


but this does not change anything. is there a way to get rid of the check
for those files beside deleting the appropriate lines from /etc/mtree/special?

any thoughts appreciated!


thanks in advance,

neys

I added
./etc/rc.d/xdm                  type=file mode=0555     optional
./etc/rc.d/xfs                  type=file mode=0555     optional

to /etc/mtree/special.local

that works! man mtree is the right place to look at.

thanks for the help.
