[WBEL-users] File corruption and new kernel

[Bob Ramstad]

Righto.  The builtin driver gives 1/20th of the performance of the
sata_sil driver.  Using the builtin driver it's about twice as slow as
a floppy.

I've run badblocks on every partition using the read write test, and
also run all the diagnostics from the manufacturer, no issues popped
up at all.

I'm a bit baffled as to what is going on...  but I do see that
sata_sil has been under constant development and I'm sure the version
in the current kernel-source RPM is old.
