Well this message is coming from drivers/net/3c59x.c in a bit of code that goes:
/* Refill the Rx ring buffers. */ for (; vp->cur_rx - vp->dirty_rx > 0; vp->dirty_rx++) { struct sk_buff *skb; entry = vp->dirty_rx % RX_RING_SIZE; if (vp->rx_skbuff[entry] == NULL) { skb = dev_alloc_skb(PKT_BUF_SZ); if (skb == NULL) { static unsigned long last_jif; if ((jiffies - last_jif) > 10 * HZ) { printk(KERN_WARNING "%s: memory shortage \n", dev->name); last_jif = jiffies; } if ((vp->cur_rx - vp->dirty_rx) == RX_RING_SIZE) mod_timer(&vp->rx_oom_timer, RUN_AT(HZ * 1)); break; /* Bad news! */ }
So basically it looks like it is taking much longer to refill rx ring buffers than it should.
On past 2.4 kernels I recall the eepro100 would report a message of "out of resources" and the fix suggested there was to increase the values in /proc/sys/vm/freepages. Perhaps it's a similar issue with the 3c59x ??
Perhaps one of the guru's could comment?
