Hi,everyone!
  I have a problem in testing the driver of my PCI-7841 card on preempt_rt linux. The driver is provided by the producer of the card.It runs well on regular linux.However, when I run it with preempt_rt linux kernel,although it's installed with no problem,the data of the can ports receive always have some errors.It just can't rightly receive the datas I transmit.Is it a driver problem?But I thought driver on preempt-rt linux should be the same with the regular one.

If the driver has been written properly in terms of locking and API then
there should be no problem after re-compiling. There is however a
sja1000 driver in kernel, I suggest you try that one.

   Looking forward to the reply.Thanks.             		 	   		  N嫥叉靣笡y氊b瞂千v豝?)藓{.n?+壏{碑郜z?"炟^n噐■?侂h櫒璀?&Ⅷ
