HP Integrity BL860c Release Note page 7

Patches and Fixes for this Version (B.11.00.07)
Fix:
• The HP-PB Token Ring driver panics during reset state.
The HP-PB Token Ring driver tries to handle control command completion interrupts
during reset state and hence it panics.
The driver code has been modified to add a check for the reset state in the control
command completion path and return without handling any control command completion
interrupts during reset state.
Patch PHNE_20536:
• The HP-PB Token Ring driver may consume all of the available IOVRs in the
system.
The driver does not combine small requests into a large one, so when it gets a fragmented
I/O request with too many small fragments from the higher layer, it will try to map each of
the fragments separately. This will consume a large number of IOVRs.
The driver code has been modified to combine small fragments into a large request so it
does not consume too many IOVRs.
• The HP-PB Token Ring driver may show too many outbound errors/discards.
One of the internal driver data structures has insufficient number of entries, causing the
driver to drop outbound packets.
The driver code has been modified to increase the number of entries in this data structure.
• The HP-PB Token Ring driver fails to rebind IP after cable reconnect.
The driver sends LINKUP and then goes through a reset cycle which can take as much as
35 seconds on cable reconnect. Since the application finds that the link is up, it sends bind
requests, however, they fail as the driver is still in reset state.
The driver code has been modified to send LINKUP only after reset completion.
Patch PHNE_18922:
• The system panics with a Data page fault when the HP-PB Token Ring driver is
present in the system.
The driver does not validate the memory range of a data structure before writing to it. This
leads to memory corruption and the system may panic.
