As soon as I plug in my new Sandisk Cruzer Micro 1GB (U3) drive, the system freezes.

The dmesg output given below shows the result from starting the system and connecting the flash drive. The hotplug feature seems to detect the drive automatically. The kernel is not throwing any messages after the device is connected, as shown below in the final messages before restart.


System:
Slackware 10
Kernel 2.4.33.3
3 USB Slots

dmesg shows:

IT is not loading the drive automatically to something like /dev/sdb1 etc.

Why dont you upgrade to kernel 2.6.*? That upgrade really solved many such problems for me.

I had already added the following three lines in /etc/fstab:

/dev/sda1 /mnt/usb1 vfat noauto,owner 0 0
/dev/sda2 /mnt/usb2 vfat noauto,owner 0 0
/dev/sda3 /mnt/usb3 vfat noauto,owner 0 0



Naveen

no dont do that ...
What I do is check in dmesg where Slackware is mounting the USB device .. (like sda1) and then mount it /dev/sda1 to some folder on my drive. That FSTAB thing is a pain.

Did you try putting the new kernel?

dmesg tells me absolutely nothing after I plug the USB in. Nothing is putout.

I cannot change my kernel to 2.6, coz I had started some work on filesystem code for ext2 for 2.4 sometime back. I was trying to use the drive as the partition where I can do some experiments.
