I'm running 2.6.14-rc4-rt6 and trying the skge driver instead of the
sk98lin and I'm getting these warnings in my logs (this is probably not
related to the rt patch):
network driver disabled interrupts: skge_xmit_frame+0x0/0x320 [skge]
No other relevant messages around that I can see. Is this a bug? Any
information I could supply to help debug it?

This is a bogus message added by the -rt patch. It is not a bug.
The trylock scheme in some newer net drivers (grep for NETDEV_TX_LOCKED)
uses local_irq_save/restore because there is no
spin_trylock_irqsave/spin_trylock_failed_irqrestore API.

Would it have any undesirable effect to find this and comment it out?
There are quite a few messages in the logs. Knowing it is not a bug I
may try the driver a bit more (I rebooted into sk98lin just in case ;-)
Thanks for the info.

Or get the -rt folks to come with a better way.

Like adding a spin_trylock_irqsave/spin_trylock_failed_irqrestore API?
