Re: cannot set up LDT for thread-local storage
I found pr 33487.
This was for dom0 i386 for NetBSD 3.99.19.
I have been running a version of firefox-linux on a dom0 i386 NetBSD-4.0
without problem. Maybe I was just lucky.
Here is additional info
Xen 3.0 i386 dom0 NetBSD-4.0 i386 dom0 firefox-linux-2 works
Xen 3.3 amd64 dom0 NetBSD-4.99 i386 domu firefox-linux-2 works
Xen 3.3 amd64 dom0 NetBSD-4.99 i386 domu firefox-linux-3 causes panic
(with LDT option on)
Is there another pr which has this issue?

Dear Xen people,
I have amd64 dom0 - xen 3.3 current as of about 9/27.
I have created two i386 domu - one NetBSD-4.0 and one NetBSD-4.99
using netbsd-XEN3PAE_DOMU from 4.99 as of about 9/27 - both domu
I have installed a firefox-bin-3.0.2 binary package or build from
pkgsrc - it seems to install fine. When I run I get:
cannot set up thread-local storage: cannot set up LDT for thread-local
Is this a limitation of NetBSD linux emulation under Xen domu?
Do you have kernel options USER_LDT?
In looking at the config for this kernel it had USER_LDT commented out (in
included XEN2_DOMU). I added that option and built a kernel - rebooted
with new kernel. When I attempt to start firefox-linux I now get:
panic: gdt_get_slot botch 1
fatal breakpoint trap in supervisor mode
trap type 1 code 0 eip c038ceac cs 9 eflags 246 cr2 bac9a000 ilevel 0
Stopped in pid 429.1 (firefox-bin) at netbsd:breakpoint+0x4: popl
That's why it's commented out :)
this is a known issue; and there's a PR open about it ...
