Looks like the trap handling for invalid segment registers on return to
user mode is broken.

That would panic in that case, yes.  For now that KASSERT() can just be
commented out until I figure out how to make that a more proper assert.

panic: kernel trap doesn't have ucred

2001-12-11 Thread Georg-W Koltermann 

Hi,

I get a panic kernel trap doesn't have ucred when I try to install
Linux ORACLE 8.1.7.

The ORACLE installation program is a JAVA application and only seems
to work with the included JRE (the IBM 1.1.8 JRE according to the
LICENSE file).

The JRE is using native Linux threads, and I know I the FreeBSD
linuxulator doesn't completely support Linux threads.  It shouldn't
panic, however.

-current was CVSuped on 12/6 at 6 p.m. CET.

Any clues from the stack trace below?  Anything else I should provide?

Regards,
Georg.
