intel atomisp 驱动bug

我在intel的E3827芯片上运行atomisp驱动时,偶发出现irq translate error,进而导致整个isp

模块无法再重新打开,且每次open video设备都会导致内存泄露。

日志信息如下:

atomisp:atomisp_isr:failed to translate irq(err=1,infos=0)

atomisp:ERROR ia_css_irq_translate failed

atomisp 0000:00:03.0:timeout 1 of 2

CSS Debug Info dump

**************************

atomisp:DFS target freq is rejected by HW

atomisp:DFS failed

atomisp:atomisp_reset

atomisp:atomisp_mrfld_pre_power_down:IRQ raised!!!

atomisp:<_atomisp_streamoff[0]

***************************

atomisp 0000:00:03.0 css init failed--bad firmware?

硬件平台:E3827

操作系统:linux kernel 3.8.0+yocto project

有哪位朋友知道该问题的原因?
