According to drivers/scsi/dpt_i2o.c, the kernel module may sleep in the interrupt handler. The function call path is: adpt_isr (interrupt handler) adpt_send_nop schedule_timeout_uninterruptible --> may sleep
A possible fixing is to replace "schedule_timeout_uninterruptible" with "mdelay". If this fixing is correct, I can send a patch. This possible is found by my static analysis tool (DSAC) and checked by my code review.
Thanks, Jia-Ju Bai
