is in the interface between
DCACHE and the processor rather than errant fetch of a line into DCACHE from
memory (otherwise the entire DCACHE line would hold corrupt data). You can see
a sample of the failure output here:
https://github.com/horshack-dpreview/ipq8065-sqrbug/blob/master
after the
failure - if they were different I restarted the test and kept looping until a
failure happened in which the ctx switch counts were the same.

Hi,
I have a strange issue on my Netgear X4S R7800. Running either DD-WRT or
OpenWrt, approximately 30-70% of my SSH login attempts fail. For OpenSSH
clients the error reported is "error in libcrypto". For the PuTTY client the
error is more descriptive - "Signature from server's host key is
generated or transformed by that
logic. Crypto is well outside my core competency so it'll be slow-going.

I also plan to look at the RSA blinding logic in buf_put_rsa_sign().
Considering the intermittency of the issue I'm thinking the issue has some
correlation or dependency to the random data generated or transformed by that
logic. Crypto is well outside my core com
- if anyone on this mailing
list has this model router can you give it a try if possible? You only need the
ipq8065-sqrbug (binary) and run-ipq8065-sqrbug.sh (script). Here's the link to

Hi,
That's
where and why the registers
aren't being preserved.

I have one of the failure paths
