(Sorry if you've seen this before; I think I sent it to /dev/null.)
This is my first try reporting a crash with crash dump info.
I've got a 486/120 PCI/ISA computer which passes the first 6 (?)
floppy-based memtest86 tests OK and can rebuild its kernel with
no problems. But it panics during FTP (under 4.5 and 4.4) and
I thought I'd try a non-PCI, non-RealTek NIC, so I put in a DEC
DE204-AB (driver "le"). Now it panics when I do this:
ifconfig le0 10.198.164.163 netmask 0xffffff00
I forgot the uname -a, but it's a stock 4.5-RELEASE with the kernel
rebuilt with the "#" removed from GENERIC's "le" option and now with
"config -g".
Boot messages:
le0 at port 0x300-0x31f iomem 0xd0000-0xd07ff irq 5 on isa0
le0: DE204-AB ethernet address ...
le: driver is using old-style compatibility shims
le0 XXX: driver didn't set ifq_maxlen
That last one looks questionable. Note that I don't know
how the NIC hardware is configured re IRQ, etc as I have
no docs and DEC didn't put info on the card. :(
The dump follows. It doesn't look helpful. Next step?
Thanks. (There's nothing below the dump.)
