Subject: kgdboe: spinlock already locked

I'm using kgdboe with kernel 2.6.5-rc3-mm4.
After a while I got this:

drivers/net/8139too.c:2098: spin_lock(drivers/net/8139too.c:c15c93a0) already locked by drivers/net/8139too.c/2098
drivers/net/8139too.c:2120: spin_unlock(drivers/net/8139too.c:c15c93a0) not locked
drivers/net/8139too.c:2098: spin_lock(drivers/net/8139too.c:c15c93a0) already locked by drivers/net/8139too.c/2098
drivers/net/8139too.c:2120: spin_unlock(drivers/net/8139too.c:c15c93a0) not locked
eth0: link down
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

All the best,

Duncan.

Without preempt, I instead get plenty of these:

eth0: Out-of-sync dirty pointer ... vs ...

(8139too.c, line 1816).

Ciao,
