We no longer do the blind scan in 2.5.39 and it seems to work fine on the big sur I tested it on: $ uname -v #33 SMP Sat Sep 28 10:58:07 PDT 2002 $ dmesg|fgrep 'Probing PCI' PCI: Probing PCI hardware on bus (00) PCI: Probing PCI hardware on bus (01) PCI: Probing PCI hardware on bus (02) PCI: Probing PCI hardware on bus (03) PCI: Probing PCI hardware on bus (04) Could it be that your i2000 has old firmware? My big sur reports the following firmware version (via Stephane's smbiosview utility): version : W460GXBS2.86E.0117C.P09.200108091154 --david
