I saw a mention of interrupt handling for forcedeth cards is the
2.6.19.1 changelog, but I still see this error in 2.6.19.1.  It started
in 2.6.19, and it didn't happen in 2.6.18.1.

Is this the same issue?  Thanks.

Nope; the issue fixed in 2.6.19.1 has always existed (provided you had 
hardware suitable to trigger it). And it was an issue of getting bogus 
legacy interrupts when using MSI, which would lead to some other device on 
the same legacy interrupt getting disabled.

I'd suggest reverting 0a07bc645e818b88559d99f52ad45e35352e8228 (fixes a 
lockdep warning, stuff with interrupts, only build tested) as a first 
guess.
