RE: [PATCH RFC 2/2] events/hw_event: Create a Hardware AnomalyReport Mechanism (HARM)

[Francis St. Amant]

Hi,

Sorry for using your BW but I wonder if you can do me a favor and remove Arthur Jones (Arthur.jones@xxxxxxxxxxxx; ajones@xxxxxxxxxxxx) from this list?  I tried to do that via the unsubscribe method at bottom but it didn't work.

Arthur has left Riverbed, and as his former manager I now get all his emails forwarded to me.  Since I'm not useful to this list, there's no reason to receive all these emails.  Probably my attempt to unsubscribe didn't work because the email came from me and I'm already not on the list--Arthur is.

Thanks very much,

I can't say I don't agree. The reference to the BIOS method was simply
to say that we need some kind of a solution for saving OOPSen and other
error info on clients too, with no pers. storage hw. And frankly, and
AFAICT, we don't have one that would work reliably on existing hw right
now :(.
