Anyway, I went to fire up netconsole to get a decent log dump and hit across the following nasty. Netconsole works fine in 2.6.23.1 with a similar config and the same kernel parameters. A shot of the screen is the only method I could come up with to capture the log, I hope that is OK, it is pretty readable. The nasty: http://andotnet.nfshost.com/linux/2.6.24-rc1-netconsole-nullderef.jpg The config: http://andotnet.nfshost.com/linux/config-2.6.24-rc1.txt The 'old' 2.6.23.1 config: http://andotnet.nfshost.com/linux/config-2.6.23.1.txt Netconsole log from successfully booting 2.6.23.1: http://andotnet.nfshost.com/linux/successful-nclog-2.6.23.1.txt The hardware, etc: eth0 : Netgear FA311 10/100Mbps ethernet adapter (netsemi driver) connected directly to another PC using a crossover cable. cpu : athlon64 3500+ compiler : gcc 4.2.2 kernel params : root=/dev/sda3 vga=0x31B nmi_watchdog=0 netconsole=@192.168.2.1/eth0,6666@192.168.2.2/00:11:d8:c0:5e:96 I hope this report is helpful and it's not too early in the release cycle, I'm still pretty new and not subscribed, so please CC :-) Btw, is it preferable for non-subscribers to use the kernel bugzilla? Or post to the list?
