ahci0: watchdog port X satapkt 0x0... timed out

Added by Florian Haake over 2 years ago

Hello,

I have Nexentastor installed on a HP N36L with a raidz1 and get some error messages in the dmesg. When this happens file transfer to nexenta stopps hand hung up. After a few seconds everything is fine again.

I have disabled hardware caching in the bios for the discs. I get this message for all four installed hard discs.

Do you have any idea what this can be?

Thanks

watchdog is usually something that will panic the system if a condition isn't met. so the core kernel is seeing bad packets on the sata bus.
