Hmmm, which kernel config did you use? I tried GENERIC and even
changed maxusers to 512 from 32 and it didn't hang. GENERIC with the
following options seems to hang it:
options MAXMEM=393216
options NMBCLUSTERS=16384
options QUOTA #enable disk quotas
options IBCS2
options SPX_HACK
# Enable the linux-like proc filesystem support (requires COMPAT_LINUX
# and PSEUDOFS)
options LINPROCFS
options COMPAT_LINUX
options PSEUDOFS
options DEBUG_LINUX
#COMPAT_SVR4 is broken
#options COMPAT_SVR4
#options DEBUG_SVR4
#device streams # STREAMS network driver (required for
svr4).
# This allows you to actually store this configuration file into
# the kernel binary itself, where it may be later read by saying:
# strings -n 3 /boot/kernel/kernel | sed -n 's/^___//p' > MYKERNEL
#
options INCLUDE_CONFIG_FILE # Include this file in kernel
#
# PERFMON causes the driver for Pentium/Pentium Pro performance counters
# to be compiled. See perfmon(4) for more information.
#
options PERFMON
options PPP_BSDCOMP #PPP BSD-compress support
options PPP_DEFLATE #PPP zlib/deflate/gzip support
options PPP_FILTER #enable bpf filtering (needs bpf)
options MROUTING # Multicast routing
# POSIX P1003.1B
# Real time extensions added in the 1993 Posix
# P1003_1B: Infrastructure
# _KPOSIX_PRIORITY_SCHEDULING: Build in _POSIX_PRIORITY_SCHEDULING
# _KPOSIX_VERSION: Version kernel is built for
options _KPOSIX_VERSION=199309L
Also, couldn't the workaround be fixed with /etc/rc.conf? As I
can see, the defaults for -current in rc.conf is:
entropy_file="/entropy" # Set to NO to disable caching entropy through
reboots.
# /var/db/entropy is preferred if / is not
available.
entropy_dir="/var/db/entropy" # Set to NO to disable caching entropy via
cron.
entropy_save_sz="2048" # Size of the entropy cache files.
entropy_save_num="8" # Number of entropy cache files to save.
harvest_interrupt="YES" # Entropy device harvests interrupt randomness
harvest_ethernet="YES" # Entropy device harvests ethernet randomness
harvest_p_to_p="YES" # Entropy device harvests point-to-point randomness
I would guess it's the last one that is hanging it.
While in older FreeBSD versions such as 4.3-RELEASE, entropy is
basically off by default?
rand_irqs="NO" # Stir the entropy pool (like "5 11" or NO).
