I tried a Linus 2.6.24-rc4 and it acts the same way, with a very slow transfer rate. =20 I also tried 2.6.24-rc4 with the older not-libata PATA drivers and it is broken. dmesg had a line about the CF card detected as hda, but /sys/block did not have hda and /dev/hda did not function. I will try the patches you mentioned, but I think I may also have to work backward through kernel versions until I find the last one where the PCMCIA hd{a,b,c,d,e} drivers worked. --=20 Zan Lynx --=-00f9FNs4S+O8bXYPfJrx Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.7 (GNU/Linux) iD8DBQBHW1reG8fHaOLTWwgRApdMAJ40DD7rBfGI683F32oRMr2JjtlFsQCeP2Vs iIlnID95w9z9u7mrRMMoUjk= =Ruya -----END PGP SIGNATURE----- --=-00f9FNs4S+O8bXYPfJrx--
