Hi,
I don't know if this is the right place to report bugs. If not, please
forgive me and route me
to the
right alias.
I use the standard Fedora Core 3 and its kernel. When I plugged a usb flash
disk( NEWMAN
128M), I could see
the system recognized this disk and automounted it in /media/usbdisk. But when
I cd into that
directory and ls. The
command will hang forever. Then from dmesg, I noticed an oops as the following.
Thanks.
