Kernels 2.6.20 cause Ultra 40 to hang on boot

[Sean Clarke]

Binary package hint: kernel-image-2.6-32

I have found a problem whereby all the 2.6.20-xx kernels cause a Sun Ultra 40 I manage to hang on boot.

The system is running a fully patched Feisty desktop installation.

Nothing appears in the logs, the system completely freezes during boot, right at the last minute - sometimes the Linux login prompt is displayed, but the system hangs a fraction of a second later (initialising HAL ?)

The last working kernel was 2.6.17-xx

The problem is 100% reproducable, the system has recently been upgraded to dual core and the "generic" kernel package replaced the existing "i386" variant and still it hangs (so both kernels appear to have the issue).

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for this particular version of the kernel. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .
However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ .
If you do decide to test with the development release of Ubuntu please comment on this bug report and include at least the minimal information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help.
