It Works For Me. (tm)

Did you build this kernel yourself or grab a debian kernel package?
Can you provide "uname -a" output of the SMP kernel you tested?

FYI, I've uploaded my a500 build (should work on j5k as well
if it's using serial console) to:
	ftp://ftp.parisc-linux.org/kernels/a500/2.4.18-pa52.tgz

The -pa52 kernel built 100+ kernels/modules successively until
I stopped it on the a500-44. The same kernel on a500-6X (PA8700)
crashes after 12 or so hours of building gcc bits. I've also seen
eth0 (tulip driver) spontaneously go to an unconfigured state
without saying anything on the console. It's possible a cron job
or something else ifdown'd it but I don't know why.

BTW, before I go to bed tonight, I expect the latest kernel to be -pa54.
I'll be adding a one-liner sym53c8xx_2 driver patch to allow one to
use the default CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1.
One can use sym53c8xx_2 now with CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=0.
Richard Hirst and Paul Bame (and a few others) have tested this out already.

thanks,
