When I recently updated by IBM T30 to the latest -stable, the system would freeze when I inserted a PCMCIA card (Xircom RBEM56G-100). Removing the card did not free the system. I had to power cycle the system to recover. If the card is already in the system, the system hangs when the device is probed. I did a binary search of patches since a known good system on 11/19 and tracked it down to this update. Without it, the card works fine, With it, the system locks up. See bug i386/74601 for a few more details. Configs and logs available on request. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
