The command line I used for testing hppa is below:

If I limit the disc transfer size of am53c974 to just 4K per transaction
(like the patch below against Linux kernel 6.6.4), then qemu-hppa
boots up nicely with qemu git head (and Günther's patches applied).
Nice detective work :)
If you're using the esp-rework-testing branch then the only patch you should need is the patch to esp-pci.c: otherwise if you also apply Günther's esp.c patch then you break the reset of the ESP_RSTAT flags when reading ESP_RINTR. Can you confirm that this is the case in your tests?
No ext4 crc errors in this case.
Mark, your git tree then still gives IRQ issues and other problems.
Presumably this is just the "Spurious irq, sreg=%02x." errors, or are you seeing something else?
Mostly spurious irq:
[ 41.561399] scsi host1: Spurious irq, sreg=10.
[ 41.562700] scsi host1: Spurious irq, sreg=13.
But later too:
