What I'd like to know is what's different about the LFDK CD that makes it work. It's a 2.6.15 kernel. Is that it? It's a ubuntu kernel. Is that it? Is there something special that the CD does? I'm gonna work on trying a 2.6.15 kernel. Then I think I'll try building the LDFK CD ISO for my distro using their docs. After that I might try installing ubuntu and seeing if that makes a different. Now, how to find the time. :) Ross > --- extract of my messages.log file --- > > > May 10 16:25:00 trinity kernel: [ 85.124000] **** Calling > device_power_up. > May 10 16:25:00 trinity kernel: [ 85.124000] **** In device_power_up. > May 10 16:25:00 trinity kernel: [ 85.124000] **** Calling > sysdev_resume. > May 10 16:25:00 trinity kernel: [ 85.124000] *** Entering sysdev > resume > May 10 16:25:00 trinity kernel: [ 85.124000] **** Resuming type 'cpu': > May 10 16:25:00 trinity kernel: [ 85.124000] **** cpu0 > May 10 16:25:00 trinity kernel: [ 85.124000] **** In __sysdev_resume, > calling class specific resume. > May 10 16:25:00 trinity kernel: [ 85.124000] **** Done > May 10 16:25:00 trinity kernel: [ 85.124000] **** Aux: > May 10 16:25:00 trinity kernel: [ 85.124000] **** Done > May 10 16:25:00 trinity kernel: [ 85.124000] ****Done cpu0 > May 10 16:25:00 trinity kernel: [ 85.124000] **** cpu1 > May 10 16:25:00 trinity kernel: [ 85.124000] **** In __sysdev_resume, > calling class specific resume. > May 10 16:25:00 trinity kernel: [ 85.124000] **** Done > May 10 16:25:00 trinity kernel: [ 85.124000] **** Aux: > May 10 16:25:00 trinity kernel: [ 85.124000] **** Done > May 10 16:25:00 trinity kernel: [ 85.124000] ****Done cpu1 > May 10 16:25:00 trinity kernel: [ 85.124000] **** Resuming type > 'timer': > May 10 16:25:00 trinity kernel: [ 85.124000] **** timer0 > May 10 16:25:00 trinity kernel: [ 85.124000] **** In __sysdev_resume, > calling class specific resume. > May 10 16:25:00 trinity kernel: [ 9002.124000] **** Done > May 10 16:25:00 trinity kernel: [ 9002.124000] ****Done timer0 > May 10 16:25:00 trinity kernel: [ 9002.124000] **** Resuming type > 'i8259': > May 10 16:25:00 trinity kernel: [ 9002.124000] **** i82590 > May 10 16:25:00 trinity kernel: [ 9002.124000] **** In __sysdev_resume, > calling class specific resume. > May 10 16:25:00 trinity kernel: [ 9002.124000] **** Done > > > > > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.
