Actually it was a simple miss by Christoph, but with my inexperience it took me a bisection and a while to get it. Both Joerg, and Stefan where able to boot with these patches and work on their machine. Jon Chelton's disks array should also work, we're testing. Submitted 2 patches. They should also be included after some testing into the 2.6.24.x stable releases. (Will be posted after some more testing) [PATCH 1/2] gdth: scan for scsi devices simple but must fatal. [PATCH 2/2] gdth: bugfix for the Timer at exit crash James please inspect and comment on this patch. It was not yet tested by the original bug submitter. In the original gdth series Christoph has forgotten to add the call to scsi_scan_host(). Jeff alternative patches did do the scan. After everything was probed, the code would loop on all found cards and scan. However I like to individually scan at each probe, because I think this way it is more ready for the hot-plug API where the discovery is done outside of the driver, and the probe is called on single host at a time. Is that right? please comment. Test away. Meany thanks to Joerg, Jon && Stefan, Cheers.
