Yes, indeed, the patch is available and I now have it. This patch can be obtained from Sun (for no charge, from what I am told). I have also made it available via anonymous ftp on procyon.cis.ksu.edu, (in pub/sunfixes/le0_patch.tar.Z) for those blessed with Internet TCP/IP access. Many thanks for all those who responded: andrew@calvin.doc.ca (Andrew Patrick) bit!markm (Mark Morrissey) Tom Leach <leach@oce.orst.edu> Steven Blair <sblair@synoptics.com> Here's an extract from the README: This patch contains a slightly modified 4.0.3[c] lance ethernet driver (if_le.c) and object files for sun3x (hydra), sun4 (stingray), and sun4c (SPARCstation1) as an effective patch for 4.0.3[c] lance xmit memory underflow ("transmission stopped"). 1. Increase LANCE_MIN_TU from 100 to 102, this effectively eliminates UFLO (!) 2. Minimize leintr lance slave register accesses - this is also a factor in UFLO. 3. Never print "Transmission stopped" or "memory underflow" error messages. This patch also fixes the panic: le0: RINT: Buffer owned by chip problem. Architecture: Sun-3x, Sun-4, Sun-4c Release: 4.0.3 Bug Report Id: 1029247, 1019513, 1029316 and 1021518 -- Joe Young jfy@ksuvax1.cis.ksu.edu
