Hi,

I just wanted to report that I always get at least one "expensive
timeout" warning per boot on a fairly recent current. Always when
accessing large data sets from NFS.

Expensive timeout(9) function: 0xc062b1bc(0) 0.102241471 s
igor# addr2line -e /boot/kernel/kernel.symbols 0xc062b1bc
/vol/src/sys/nfsclient/nfs_socket.c:1357

I also got one from syscons, but I've since removed the flags from
rc.conf, as the machine is headless. For the curious:

Expensive timeout(9) function: 0xc04a1444(0xc07a2880) 0.008804956 s
igor# addr2line -e kernel.symbols 0xc04a1444
/vol/src/sys/dev/syscons/syscons.c:1688

I have kern.hz=100 in /boot/loader.conf, if that is important.
