>Release:        NetBSD 11_BETA
>Organization:
Knights of the CISCadel
>Environment:
NetBSD 11_BETA on MVME177
>Description:
Denis Ahrens has reported FP problems on an MVME177.  The issue is receiving SIGILL for FP instructions that should be emulated by the 060SP.
>How-To-Repeat:
Boot an MVME177 and note that a handful of processes that use FP will receive SIGILL during boot.  The log(3) function is an example of one that will fail.
>Fix:
There was an error in re-factoring the vector initialization code.  A fix is in progress.
