Dear Hackers, after upgrading to the recent (as of this weekend) -current i'm having a 100% reproducible panic.
the card i'm trying to make to work is RealPort Ethernet 10/100 + Modem56 (REM56G-100) it does work in Linux in W2K, it did not work before upgrade, but at least it did not panic. i have attached /var/log/messages and gdb dump and wide open to any suggestions. thanks, max
