Package: linux-2.6 Version: 2.6.32-bpo.5 Severity: critical Tags: squeeze patch lenny Justification: breaks the whole system
http://marc.info/?l=linux-netdev&m=127240304211909&w=2 here is the description from the mail , repeated: It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.
