Hi!
Sometimes when I boot my notebook it freezes at "configuring kernel parameters". No kernel messages, no syslog entries, but the system echoes keyboard input. Ctrl+C doesn't work, though. It seems like /bin/sysctl itself hangs and not the kernel.
Any solutions apart from disabling sysctl in the bootmisc init script?
| /etc/sysctl.conf: | # /etc/sysctl.conf
#
# For more information on how this file works, please see
# the manpages sysctl(8) and sysctl.conf(5).
#
# In order for this file to work properly, you must first
# enable 'Sysctl support' in the kernel.
#
# Look in /proc/sys/ for all the things you can setup.
#
#enable laptop mode
#vm.laptop_mode = 5
#vm.dirty_expire_centisecs = 3000
#vm.dirty_writeback_centisecs = 3000
#vm.dirty_background_ratio = 5
# Disables packet forwarding
#net.ipv4.ip_forward = 0
# Disables IP dynaddr
#net.ipv4.ip_dynaddr = 0
# Disable ECN
#net.ipv4.tcp_ecn = 0
# Enables source route verification
net.ipv4.conf.default.rp_filter = 1
# Enable reverse path
net.ipv4.conf.all.rp_filter = 1
# Enable SYN cookies (yum!)
# http://cr.yp.to/syncookies.html
#net.ipv4.tcp_syncookies = 1
# Disable source route
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv4.conf.default.accept_source_route = 0
# Disable redirects
#net.ipv4.conf.all.accept_redirects = 0
#net.ipv4.conf.default.accept_redirects = 0
# Disable secure redirects
#net.ipv4.conf.all.secure_redirects = 0
#net.ipv4.conf.default.secure_redirects = 0
# Ignore ICMP broadcasts
#net.ipv4.icmp_echo_ignore_broadcasts = 1
# Disables the magic-sysrq key
#kernel.sysrq = 0
# When the kernel panics, automatically reboot in 3 seconds
kernel.panic = 20
# Allow for more PIDs (cool factor!); may break some programs
#kernel.pid_max = 999999
# You should compile nfsd into the kernel or add it
# to modules.autoload for this to work properly
# TCP Port for lock manager
#fs.nfs.nlm_tcpport = 0
# UDP Port for lock manager
#fs.nfs.nlm_udpport = 0

| Okay, now I know that this seems to be a problem with hwclock/rtc. It also happens without sysctl being started and I found several reports about problems with the clock causing the system to hang. Looks like this one: http://bugzilla.kernel.org/show_bug.cgi?id=9511 |
