Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I'm running 0.7pre7 2004/06/01.  The (initial) primary is an FC2 2.6.5
and runs fine, save for eventually noting that the connection to the
secondary was lost.  The secondary is a FC1 2.4.22 machine and loads the
module fine, but shortly after starting to sync I get several oops (see

After this happens /proc/drbd shows a connection state of
NetworkFailure and the modules used count is at 1.  I tried to 'drbdadm
disconnect..' (hoping to follow with a detach and rmmod), which results
in another oops and drbd's used count jumping to 3.  Needless to say,
I'm left to reboot the machine.

I'm using 100MB NICs (in half duplex) and have noticed that if I drop
the sync rate to 1MB or less it seems fine for longer than the usual ten
seconds.  I've only just started a sync at 500k, and at this rate I'll
know some time tomorrow (barring an oops) if it's actually succeeded.

	With regards,

P.S. Is attaching the oops the best way to go?  I figured it'd get
mangled when it wrapped if I did it in-line..
