I think $(subject) says it all.

I have a Gigabyte AM2 mobo with an AMD64 X2 CPU installed.

The SCIS set up looks lie this:

29160N <--> da0 <--> da1

da0 has a 32-bit installation of FBSD-8
da1 has a 64-bit installtion of FBSD-8

If I install 4GB of memory (4 DIMMs) in the system I see the following
behavior:

a) booting from da0 works just fine and I can access both disks without
any problem.

b) booting from da1 results in (apparent) data errors such that /bin/sh
dies with SIGILL and /rescue/sh dies with SIGSEGV.

c) trying to do an installation of a snapshot of FBSD-8 to a SCSI disk
results in various problems, among others a kernel panic in ffs_balloc
during newfs.

d) an installation to a SATA disk succeeds and the system runs just
fine.

With only 3GB of memory everything works. Of course, I'd really like to
be able to use the entire 4GB. And I want to keep my SCSI disks.

Hey guys,

Is there any known reason why sdparm would dump core on my 6.2-STABLE
install? I'm using an Intel SRCMRU 0-channel RAID in conjunction with an
on-board Adaptec AIC-7902 controller.

Thanks,

Brad Waite

Below are some pertinent DMESGes:

FreeBSD 6.2-STABLE #0: Sun Jul 15 08:40:35 MDT 2007
CPU: Intel(R) XEON(TM) CPU 2.00GHz (1994.13-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0xf24 Stepping = 4
Features=0x3febfbff

Thanks. I am using seperate (but identical) machines.

Also, geom_gate works perfectly (well, as well as it normally works,
which is not great but serviceable). I was hoping to replace geom_gate
with iSCSI.

Hi!

I have been testing iSCSI initiator using two 7.0-RC1 machines.
Machines are quad-core Xeons connected back to back via gigabit. The
target is running the same OS with the iscsi-target port talking
directly to a local device partition on disk.

While it seems to work well initially (I can format, fsck, and mount a
disk) after I start copying files in and out it seems to lock up
regularly for about 15-20 seconds a time. After it unblocks it
continues as if nothing happened until 5-10 seconds later it happens
again (and again).

Is this a known problem and is there any workaround?

Here's a linux dmesg with the below adaptec suggestions applied. Same
