Thanks in advance for testing.
I've given the new driver a run on my U1. A bit of history before the
results: 2.6.13 (aurora 2.0) esp driver works well on this machine.
However, 2.6.20 stock does not: it dies with DMA errors after
(correctly) identifying the disks. (I can get the exact errors, if
they're useful.) So this was my motivation for trying the new esp.
I patched 2.6.20 with...
- [SPARC64]: Fix SBUS IOMMU allocation code
- [SCSI]: Fix scsi_send_eh_cmnd scatterlist handling
- new esp driver
- esp_enable_interrupts "I need my head examined" patch
I hit a small build glitch: Wwith the new driver, the combination...
CONFIG_SCSI_SPI_ATTRS=m
CONFIG_SCSI_SUNESP=y
...gives...
LD .tmp_vmlinux1

make: *** [.tmp_vmlinux1] Error 1
Switching to...
CONFIG_SCSI_SPI_ATTRS=y
...cures that.
Booting with the new driver I see very similar behavior to 2.6.20 stock:
Devices are correctly identified, then DMA errors kick in. I suppose
this is interesting because it implies the breakage between 2.6.13 and
2.6.20 may have been outside the esp driver itself. Full dmesg with
esp.esp_debug=2047 is below. There is a single target on the bus at id
1. Although I haven't tried it with the new esp, previously moving the
target to different ids and adding/removing targets had no effect.
