I am experiencing the same problems Styno describes in this closed thread.
In my case I am using a 1GB Kingston DataTraveler USB pen drive. Everything was working fine for almost 2 months (with many restarts in between). Now it has become very unstable. Sometimes I can boot from it sometimes I can't. I can not reproduce the problem. The USB pen drive works fine when using it in other Linux machine.
I have checked the pen drive with badblocks using -F option and everything went fine: no bad block.
I have deleted all partitions and reinstalled everything back in the pen drive as it was before but the problem persists. I took an old hard disk, configured exactly the same as it is in the pen drive, copied all same files into it and it boots perfectly.
It seems to me that pen drive has lost some of its characteristics I can not come up with.
Here you go the log at boot time with the pen drive plugged in. There you can see some strange things when it comes to the USB part.
Some idea?Code:Jan 1 01:00:02 kernel: ip_conntrack version 2.1 (128 buckets, 1024 max) - 344 bytes per conntrack Jan 1 01:00:02 kernel: ip_conntrack_pptp version 1.9 loaded Jan 1 01:00:02 kernel: ip_nat_pptp version 1.5 loaded Jan 1 01:00:02 kernel: ip_tables: (C) 2000-2002 Netfilter core team Jan 1 01:00:02 kernel: ipt_time loading Jan 1 01:00:02 kernel: NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.

PS: Things has become worst since I can not boot from it any loger but everything seems Ok with the pen drive.
