Yes, I can reproduce bug in -DEVEL (10 Jul 2007). But I can not understand, it
is the same bug or not.
thanks for your report. this indeed looks very serious.
Condition for 100% bug reproducibility:
1. System installed to USB HDD (USB box vendor 0x05e3) and booted from it. USB
box connected to right USB slot of Dell Latitude X1 laptop.
2. USB box JMicron connected to left USB slot, file system UFS created and
mounted to /mnt.
3. cp -R /home/dcvs /mnt process started.
There is kernel panic "vm_fault: unrecoverable fault at 0x**** in entry 0x****"
or many "bad block ****, ino ****" messages after 2-15 minutes.
is any of the source filesystems damaged after that?
