Indeed, that's what it was 8-] It's working just fine now, thanks!
I'm still fighting with the recent 2.6.20 as it doesn't seem to
recognize my disk, but 2.6.17 is fine as well so far. Just dm-crypt is
*very* strange:

/dev/hda5 is not mounted or anything, and the second luksDump command
came just a second after the first one. WTF?!

And BTW, HD performance leaves much to be desired---is this normal for
a 250 MHz MIPS? My 68040/40 Amiga did not much worse over its 7 MHz bus:
| ann ~ # dd if=/dev/zero bs=1M of=/dev/hda5
| dd: writing `/dev/hda5': No space left on device

| multcount    = 32 (on)
| IO_support   =  1 (32-bit)
| unmaskirq    =  1 (on)
| using_dma    =  1 (on)
| keepsettings =  0 (off)

| readahead    = 256 (on)
| geometry     = 19846/16/63, sectors = 20005650, start = 0

I was planning to put a partly crypted drive from my HPPA box in there,
and I hoped at about twice the clock it would perform better...

cheers!
