Re: GENERIC 5.1.2 panics on 7248/120

Thanks all, now I catched the culprit: the combination of if_we and
pnpbus. I noticed there were garbage characters from if_we in the first
dmesg I posted. So I disabled the if_we from the GENERIC kernel:

< we*   at pnpbus?                      # WD/SMC Ethernet
---
> #we*  at pnpbus?                      # WD/SMC Ethernet
372c372
< we1   at isa? port 0x300 iomem 0xe8000 irq 11
---
> #we1  at isa? port 0x300 iomem 0xe8000 irq 11

And now the kernel boots (console output attached).

The card is an IBM genuine ISA board and I can even configure it in the
System Management Services menu. The installer kernel recognizes the
card without the pnpbus and causes no panic.

(we1 messages in the dmesg of the installer)
we1 at isa0 port 0x300-0x31f iomem 0xe4000-0xe7fff irq 11
we1: WD8013EBT Ethernet (16-bit)
we1: Ethernet address 00:20:35:56:87:4f

(console output from the modified GENERIC kernel)
