query on kernel err: ata1: link is slow to respond, please be patient
by simonkbaby from LinuxQuestions.org on (#5D7JP)
Hello,
I am new to this forum. I am working with an embedded system with linux kernel version 2.6.32 (MontaVista Linux G++ 4.4-111220) ) on cavium processor. I have a boot CF card, removable CF and an SD card interface. I see after cold reboot the boot CF card is not able to detect by the kernel (not always). The kernel logs shows below warnings and errors during this problematic condition. In the good case I am not seeing the below logs from kernel. Can someone help send some clue or root cause. The Boot CF card seems to be working. Is this issue between kernel and the driver interface ?
