SubjectRe: assertion (cnt <= tp->packets_out) failed
Someone asked if I could try to trigger this assertion again, and I'm 
afraid I probably cannot, I didnt do anything special at the time. But
I've got something even better for you all, got a BUG from something
tcp-related. Mind you, I am trying to find a possibly hardware-related
issue here, so if this bug does not make any sense it might be my hardware!

I would actually want to know it if this is likely hardware-related or
not, since I have no idea if its RAM, CPU, motherboard or "only" a disk
that is broken. I know _something_ is broken, due to lockups, and seeing
a faulty disk indicated in a HDD diag, but only once, the disk is
apparently fine 99% of the time.
