It seems that the locking problem we were experiencing was related to
the disparities of drives in a raid 0 array; when we replaced the
6Y200M0 with another 6B200S0 the problem never reappeared even after 1.8
TB of io. Thanks a buch to Eric for pointing out the differences; the
promise card and/or driver must have a problem with the bridge chip on
that drive when interfacing with another drive that does not have that
chip. We also tested for performance improvements with
writel(tmp, mmio + PDC_TBG_MODE);
commented out from pdc_host_init, but it does not cause a significant
difference when benchmarked with bonnie++.
Thanks for your help,
Francois
