Which arch were you running on and how did you set up your serial console? I have not seen the intermittent stall problem you described before. > Any > ideas of where I can start?

That is true. You can look at the ChangLog at kdb/ and at arch/{ia64,x86}/kdb/ directories. Major bug fixes/features are described in the ChangeLog's. Unzipped patches will have complete version of ChangeLog's. BTW, uhci USB feature has been backed out since it caused regression in ohci. > I guess perhaps I could search > the mailing list archives for the original patch submissions... any > easier way?

Yes, it has been that way. We use internal RCS tree to maintain the patches and newer versions are then placed at the FTP site.
