No, I mean I'm running into problems trying to get a 64-bit kernel to work. Two problems - one I could work around, one I can't. First is as soon as any kernel I've tried gets to enumerating EISA devices it hangs. The panel LEDs flash in a specific pattern. I think I remember reading about how each pattern is one nybble of an error code (wow - I don't remember the last time I got to use the word 'nybble'). I should prolly do a ToC and grab the data for reporting, just haven't got around to it yet. Now, I know for a sure it's at the EISA point in a 2.6.13 kernel as I can tell from the messages. I think something changed in recent kernels so that kernel messages are shown sooner in the boot process. Earlier kernels would just hang after about the same amount of time, but I wouldn't see the message. The LED pattern is the same in all cases, regardless of kernel version. BTW - can someone confirm my kernel message theory? Whoever made that change, thanks. :) Anyways, if I disable EISA in the kernel, I get up to the SCSI driver it hangs for about a minute then spits out a message about offlining the drive: ncr53c720-0: rev 0xf irq 67 ncr53c720-0: ID 7, Fast-10, Parity Checking, Differential scsi0 : ncr53c8xx-3.4.3g scsi: Device offlined - not ready after error recovery: host 0 channel 0 id 0 lun 0 Kurt. _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
