X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 20 Jan 2004 11:39:55 -0000 I've been seeing what appears to be some instability with my aironet driver since switching to 5.2-CURRENT. I also did a recent checkout and recompile and am still seeing it. Every once in a while the card will simply diasppear. Other times the machine simply reboots under heavy network activity without a single error message to syslog or console. If I let the machine just sit there for a few hours without much network activity aside from random DHCP requests, I will eventually see something like: Jan 19 06:53:20 Mocha kernel: Jan 19 06:53:20 Mocha dhclient: send_packet: No buffer space available Could I really be running out of mbufs? I'm using kernel autoscaling/autosizing. I'm not certain all these incidents are related. They're certainly repeatable. The hardware is an IBM ThinkPad T30 with a Cisco 350 MPI (miniPCI) card. Hardware revision: [ 00:ff ] Software revision: [ 05:00 ] Software subrevision: [ 00:01 ] Interface revision: [ 00:00 ] Bootblock revision: [ 01:59 ] I know the information I have isn't very detailed. If someone could point me to better debugging techniques, that would be great. -- /*===================[ Jake Khuon ]======================+ | Packet Plumber, Network Engineers /| / [~ [~ |) | | --------------- | | for Effective Bandwidth Utilisation / |/ [_ [_ |) |_| N E T W O R K S | +=========================================================================*/
