|If you aren't already using it, sup (or ftp) the new /sys/i386/isa/isa.c and
|rebuild your kernel. It fixes all sorts of obscure (eisa/vesa) problems with
|just one line :-)
Yep, thanks, the isa.c fix that Justin provided did fix
certain symtoms with an adaptec 1742 eisa/scsi adapter
here.
But I still see remaining problems even with that fix.
That is, the backtraces I've posted before and those
below are for kernels that have included Justin's isa.c
fix. Rich
