Still happens with 2.6.37-rc2-git4.

Still happens with 2.6.37-rc5.

Still happens on 2.6.37-rc7.
Comment 4 Randy Dunlap 2011-02-07 04:03:19 UTC 
I cannot reproduce this problem on 2.6.38-rc3.  Nothing has
changed in the driver source code AFAICT: drivers/spi/spi_lm70llp.c
has not been updated since June 30, 2010.

Please close this bug report.

This looks like some race condition (the dmesg is all messed up...)
Probably somewhere a missing locking. Maybe some fallout of bkl removal?

I'm closing it as unreproducible for now.
