I am also getting an interrupt storm with FBSD 7.1 and tried Oliver-H suggestion to raise the interrupt threshold in /etc/sysctl.conf
My /etc/sysctl.conf:
Quote:
# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
sysctl.hw.intr_storm_threshold=400
|
My vmstat -i

$ vmstat -i

What I am wondering is if I can disable rl and rlphy as I'm not using the NIC card. Can this be done short of compiling a new kernel (/boot/device.hints vs /etc/sysctl.conf ?) or the old BSD way? >ukc
