2. Version History
6.2.34 - Fix locking regression instroduced in 6.2.29 that
could cuase a lock order reversal between the io_request_lock
and our per-softc lock. This was only possible on RH9,
SuSE, and kernel.org 2.4.X kernels.
6.2.33 - Dynamically disable PCI parity error reporting after
10 errors are reported to the user. These errors are
the result of some other device issuing PCI transactions
