Hello,
My U2E (without any hardware trouble, I have tested it with SUN vts)
randomly oopses (an oops by week...). I use a debian/testing with
2.6.23.8 official kernel.
fermat:[~] > uptime
14:41:03 up 11 days, 3:25, 5 users, load average: 1.24, 0.70, 0.35

Linux fermat 2.6.23.8 #1 SMP PREEMPT Thu Nov 22 11:55:54 CET 2007

Of course, this kernel was built with gcc-4.1. Last Oops is :

Any idea ? I have seen the same Oops with 2.6.23.1. U60 I use with the
same configuration do not seem to have the same trouble.
