The most common machines that +exhibit these problems are Gateway 2000 machines with PHOENIX bios's but +other machines with PHOENIX bios also exhibit this behavior. + The temporary solution until you can get the distribution +installed on your hard-drive is to 'bounce' on a key like shift or +num-lock (which works well since you can see when the keyboard comes +back to life) until the boot sequence is finished. The keyboard will +work fine for installing FreeBSD onto the hard-drive. + Generally the problems go away at this point, but if it doesn't +you should install a SYSCONS kernel which doesn't experience these +keyboard problems. + +/usr/bin/gdb: + The gdb in the release will not work on shared objects nor will it + work with C++ executables. Please use the gdb in the ports area for + debugging shared and/or C++ code. This is just a work-around until + we can transition to the new version of gdb completely. See below. + +/usr/gnu/bin/gdb: + This is the gdb from the ports area (if installed), also known as + gdb-4.11. There is a problem using gdb-4.11 to debug a core-file + generated by a binary which uses shared libraries. The problem is + basically due to the fact that the shared libraries are mmap'ed at + addresses in the memory space of the binary which are not accessible + to gdb-4.11 at the time that it tries to examine the core-file. This + usually manifests itself in "Cannot access memory at address <foo>" + messages at startup and "#0 <bar> in end ()" when you try to do + a backtrace ("bt"). + + Workaround: start gdb-4.11 without reference to the core-file, + e.g. "gdb fubar". Set a breakpoint in main and run the inferior + so that gdb-4.11 can resolve references to the shared libraries. + After this, use the "core-file" command to force gdb-4.11 to + load the core-file, e.g. "core-file fubar.core". Since all + shared library references were previously resolved gdb-4.11 can + now access the shared libraries and things like "bt" now work. + You will also be able to reference items previously on the stack + (from the core file), but all globals will show up as zero'd. + All these problems may be avoided if you compile the application + with -static. + +/sys/i386/isa/if_ep.c + The 3c509 driver will hang under heavy network loads and take your + machine off the network. (Though the machine will continue to run with + no network facilities) + + Workaround: Try a "ifconfig ep0 down" and a "ifconfig ep0 up" + to get it running again. + +/sys/i386/isa/bt742a.c + The Bt445S and Bt747 controllers can cause problems when ISA DMA + is selected as an option. With the EISA controller the remedy is + easy - simply turn it off using your EISA configuration utility. + With the Bt445S, which is a VLB card, you must switch the undocumented + "SW10" on "SB2" to the off position. Also note that certain revisions + of the Buslogic board (Revision C or earlier, firmware revision <3.37) + will cause DATA CORRUPTION with systems containing more than 16MB of + memory. If you find this to be the case, temporarily remove your + extra memory and contact Buslogic for an upgrade! + +/usr/bin/find + find doesn't work on CDROM's. You need to call find with the + "fstype isofs" argument to get it working. The bug seems to be + in the "fts(3)" routines that find uses. + +/usr/bin/awk + awk dumps core for the following command line "awk '' blubber". + Problem is already known by the gawk maintainers and will be fixed + in the next release of gawk. + +$Id: KNOWNBUGS,v 1.7.2.6 1994/05/01 20:58:17 rgrimes Exp $ |
