Hi Matt,

Thanks for the hints,

I think you meant the link pointing to:

I did it mainly putting it as option in /boot/grub/grub.conf as you can see:

[root at sparkbox log]# cat /boot/grub/grub.conf | grep lun
        kernel /vmlinuz-2.6.9-34.ELsmp ro root=/dev/VolGroup00/LogVol00
selinux=0 vga=0x031a max_luns=32
        kernel /vmlinuz-2.6.9-34.EL ro root=/dev/VolGroup00/LogVol00 selinux=0
vga=0x031a max_luns=32

Rebooted and the same as previously noted.

Could be something related to hald/hotplug? Should i increase the max_luns value?

It's a usb card reader as you can see:

[root at sparkbox log]# lsusb | grep TEAC
Bus 001 Device 006: ID 0644:0200 TEAC Corp.

I have to say that i have another host with the same problem with a different
card reader.

Thanks again for your hints,
