Hi,
I was testing our iSCSI initiator driver on linux-2.6.4. The host
machine had Ethernet Pro 100 ethernet cards using which iSCSI sessions were
established. Few minutes after starting I/O on iSCSI disks the following
messages started appearing on the console:

Apr 12 12:04:17 linux-2 kernel: eth1: RxAbort command stalled
--------------------------------------------------------------------------------
After this eth1 ceased to function until the system was rebooted.
Even ping failed.
I tried the same test on another machine which had a different n/w card.
Though I saw messages about page allocation failure, the card continued to
function normally.
I was wondering if this is a bug in ethernet pro 100 driver. Please let
me know in case I am wrong.
Thanx
