Hi!
I'm using debian sarge and wanted to change from the 2.4.27 kernel to
the 2.6.8 kernel.
But under the 2.6.8 kernel my usb memory stick is not working. Not
only this - if I plug it out the whole system crashes!
Under 2.4.27 when I plug in the memory stick dmesg shows:
hub.c: new USB device 00:07.4-2, assigned address 2
usb.c: USB device 2 (vend/prod 0x4e8/0x111) is not claimed by any active driver.
Initializing USB Mass Storage driver...

lsmod shows these additional modules:

sd_mod 10732 0 (autoclean) (unused)

I than can mount the stick. One more module is loaded (nls_cp437) and
dmesg adds:
SCSI device sda: 256000 512-byte hdwr sectors (131 MB)
sda: Write Protect is off
/dev/scsi/host1/bus0/target0/lun0: p1
Under kernel 2.6.8 I get plugging the memory stick in:

lsmod shows just:
usb_storage 68800 1
But then trying a mount the mount command hangs and plugging the
memory stick out the whole system hangs (without any error message in
the logs).
Any help?
Thanks a lot in advance!
