EJ, Dave:

We got another "2nd ADC timing error" event last night on h1iopoaf0. The previous one was Wed 11aug2026 on h1iopiscex (alog 91508). Unlike the h1iscex one, h1iopoaf0's cpu did not spike, but it is running high anyway. No dmesg log was generated.

It is looking more likely this is software and not an issue with the second Adnaco backplane as postulated in the 11th Aug alog.
