thread_get_info_callback: cannot get thread info: generic error

[Bharadwaj Yadavalli]

I get the error 
   
    thread_get_info_callback: cannot get thread info: generic error

when running on a Linux/IA64 box. Here are the details

Would someone know what the problem is? I set LD_ASSUME_KERNEL
to make gdb use /lib/libthread_db.so.1 instead of the default
/lib/tls/libthread_db.so.1. I get a similar error.
