Scott replied: The kernel isn't hung, it's just forever waiting for an interrupt from the amr card that it'll never get. Again, this is almost certainly an interrupt routing problem, so please contact John Baldwin <jhb at freebsd.org> and provide him your details.

After reading this http://lists.freebsd.org/pipermail/freebsd-current/2005-July/052434.html I breaked into the debugger and posted this http://lists.freebsd.org/pipermail/freebsd-current/2005-July/052489.html Is the information there suficient to open a PR? > > If you can't get into the debugger, it's more likely an interrupt/etc > problem. We might try John Baldwin (jhb@) as a possible first contact. John started debugging this with another person with similar problems on 5 and the debugging never got to 6 (no feedback from the other person): http://lists.freebsd.org/pipermail/freebsd-current/2005-July/052727.html > > Robert N M Watson > _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
