Package: linux-image-2.6.26-1-sparc64 Version: 2.6.26-11 Severity: important
Hey, I have a Sun Netra T1 200 with two ethernet ports on a sungem card. eth0 has no cable connected, eth1 is connected to a regular 100BaseT switch. When I boot up the box, I get flooded with eth0: switching to forced 100bt eth0: switching to forced 10bt But the box is stable and I can do everything with it. However, when I try to "ifup eth1" (both interfaces have no "auto" lines in /e/n/interfaces), the box gets stuck, prints a soft-lockup and isn't responsible anymore. The lockup looks like this: [ 361.852604] BUG: soft lockup - CPU#0 stuck for 61s!

However, I wasn't able to properly revert it to test the bug. Hope some of you sparc guys have some idea how to fix that, as this is a imho bad regression from Etch.
