I'm also sure it did not fix the reset problem.
I think there are other resources that are not freed after a reset.
My experience is that once a device causes a reset, it never recovers,
as if the kernel is still waiting for some pending I/O on the device.
Any further attempts to access the device cause the process to hang in
disk wait.
It's trivial for me to reproduce this, if someone wants to give hints
on how to debug this, or what data structure to grovel through to check.
The AHA1542 is a very good ISA card. It's hard to beat for ISA. However,
the 2.2 linux drivers for it are substandard. The drivers in 1.0 were
much more stable.
