Hello, I am developing a device driver for the AxiomTek AX5621H data acquisition card, and I am encountering some problems on a particular machine. This driver works pretty fine on normal machines, but crashes on an Industrial PC with intel 830 2-piece board (with the main board going into a PCI and an ISA slot on the expansion board(which houses all the PCI, ISA and AGP slots) at the same time. The error I get is given below :
CPU 0 : Machine Check Exception : 0000000000000004 Bank 0 : a200000084010400 Kernel panic : CPU context corrupt In interrupt handler - not syncing The DMA channel I use is DMA1, and i check for free interrupts and then allocate them accordingly. So there is no conflicts, I assume. Also there are no conflicts on the address range I have allocated (It is for now 0x300). The card supports only DMA channels 1 and 3. I have tried both, to the same result. If anyone among you have had experience with such a problem, any help in fixing this matter would be of great help. Thank You. Harish Harshan. ----------------------------------------- This email was sent using Amrita Mail.
