According to drivers/net/ethernet/3com/3c59x.c, the kernel module may 
sleep in the interrupt handler.
The function call paths are:
boomerang_interrupt (interrupt handler)
   vortex_error
     vortex_up
       pci_set_power_state --> may sleep
       pci_enable_device --> may sleep

vortex_interrupt (interrupt handler)
   vortex_error
     vortex_up
       pci_set_power_state --> may sleep
       pci_enable_device --> may sleep

I do not find a good way to fix them, so I only report.
These possible bugs are found by my static analysis tool (DSAC) and 
checked by my code review.


Thanks,
Jia-Ju Bai
