scp 3.1p1 problem on Solaris

[Lars Hecking]

 I have removed ANDIrand from my Solaris8 system and installed patch
 112438-01 which provides native /dev/random and /dev/urandom devices.
 Recompiled both openssl-0.9.6c and openssh-3.1p1, restarted sshd.

 Now I seem unable to use scp, and connections to the local sshd appear
 to be very slow.

$ scp php-4.2.0.tar.gz user at remote:/WWWserv/src
local at bastion's password: 
php-4.2.0.tar.gz       6% |*                            |   224 KB  - stalled -

 When I'm trussing this scp process, I find that the following
 output repeats over and over at some stage:

...
    Received signal #14, SIGALRM, in write() [caught]
write(7, " AF8 d >FF z y 9FF02 z x".., 8192)    = 5120
ioctl(1, TIOCGSID, 0xFFBEDE34)                  = 0
getsid(0)                                       = 508
ioctl(1, TIOCGPGRP, 0xFFBEDE9C)                 = 0
ioctl(1, TIOCGWINSZ, 0xFFBEDEF8)                = 0
write(1, "\r p h p - 4 . 2 . 0 . t".., 80)      = 80
sigaction(SIGALRM, 0xFFBEDFF8, 0xFFBEE078)      = 0
alarm(1)                                        = 0
setcontext(0xFFBEE1E8)
...

 Has anyone seens this before? Is openssh at fault here, or is it openssl?
 openssh configure: --prefix=/opt/ssh --without-rpath --sysconfdir=/etc .
