Reporting an issue that is causing my SunBlade 100 (ultrasparc64)
workstation to be unable too boot. I've identified the release this
problem was first introduced 6.8, however the problem remains unresolved
in 6.9 and seems to be in even worse state in 7.0 and -current.
Net booting appears to be functional, and I can install from a netbooted
ram disk without issue in any version (6.8, 6.9, 7.0, -current).
Booting from the hard drive after installation is not working since 6.8.
The system installs and appears to be working correctly in versions 6.3,
6.4, 6.5, 6.6 and 6.7. Specifically, it appears to me that the
workstation hardware is working correctly, and a software bug was
introduced between release 6.7 and 6.8 that is causing the issue.
Attached is a 6.8 kernel panic (I can provide this for 6.9 as well but
not for 7.0 or -current because the kernel doesn't even load on those
versions at all). For example on -current all that I get on boot is this:
