You have right I just reinstall an external disk on lasi700 (53c700) cont=
roler
and boot a 64bit kernel (with ncr53c8x as module) :-)

BUT it is horribly slow:
    o it takes about a 1.5 h to boot (about 5 min for its twin 32bit)
    o a ssh connection takes about a min too (only some seconds for 32bit=

kernel)

and fwiw top:

just show an 100% idle system?

Another known issue for this kind of d model?

Any idea?

Thanks,

btw: I read this strange messages when it init raid5

while the 32bit showed me more relevant values:

md: raid5 personality registered as nr 4

obviously I remove also raid5 support but it doesn't help :-(
