Subject: bnx2x machine check in bnx2x_ack_int()
Hi Eilon,
I'm using bnx2x 1.45.23 from RHEL5.3s4 on a prototype ia64 platform,
and I see intermittent machine checks at bnx2x_ack_int+176, which is
just after __ia64_readl() returns.
This is a proto with incomplete firmware, and the driver correctly
complains about that, but it seems like there's still a hole where
things blow up.
The machine check happens intermittently on boot, but I can reproduce
it instantly with a loop like this:
# while /bin/true; do ifup eth6; date; done
Here's some lspci and dmesg information. I added a little debug in
bnx2x_ack_int(), so this is a kernel I compiled myself.
Let me know if there's any information I can collect or testing I
can do.
Thanks,
Bjorn
