>Environment:
Not available - problem during initial installation
>Description:
Attempting to reinstall 4.1.1-RELEASE from a local FTP server (running
FreeBSD 4.0) onto a Toshiba Libretto model 30CT via Ethernet using a
3Com 3C589D on the Libratto; Libretto floppy drive is also connected via
a PCCard interface; FreeBSD 4.1-RELEASE installed successfully using the
same methodology:
 1) If I attempt to remove the floppy PCCard to replace it with the
    3C589 (as worked with 4.1) I get a report "ep0: No irq?!" on the
    debug screen. The replacement is done at the point where I have
    selected a set of IRQs for the PCCards.
 2) If I leave the floppy PCCard in place I do not get this message;
    however the PCCard is detected and declared to the kernel but is
    allocated IRQ 5 *which is not in the set I have selected as free
    IRQs* (the set is 10, 11, and 15); installation proceeds for a
    while but fails when actually trying to read the first file in
    the "bin" distribution set - it gets "stuck" and I suspect a
    "lost" IRQ

Please note that I have found with various earlier versions of FreeBSD
that on this machine I should set the PCIC into "polling mode" by
selection IRQ number 0 (meaning none) for the PCIC itself. I did this
using the configuration editor command "irq pcic0 0" on all my
attempts to install 4.1.1.

Since the installation got to the stage of initialising the filesystems
before getting "stuck" i now have a machine I can't use; I could
reinstall 4.1 but am reluctant to do so if this can be solved fairly
promptly. I wanted to use the most up-to-date version of OpenSSL to
generate a "root" certificate for a certificate authority.
