I received this oops earlier today. The system is a Gigabyte 586DX
m/board with 2xP90 (both stepping 5), onboard aic7xxx and onboard
IDE. 512kb trident video card and ne2000 clone network card.
Vanila 2.1.43 (SMP) kernel.
I had been getting the following messages intermittently all day:
--8<--8<--
Jun 30 14:42:29 library kernel: eth0: timeout waiting for Tx RDC.
Jun 30 15:04:09 library kernel: eth0: Interrupted while interrupts are masked! isr=0x2 imr=0x0.
Jun 30 15:56:43 library kernel: eth0: Tx request while isr active.
--8<--8<--
I hope that this is of some use.
