Hi Guys,

I ran 2.6.18-rc2 with libata patch. I have seen many occurrences of EH
traces in dmesg log as show below:
...
[30540.003174] ata1: exception Emask 0x10 SAct 0x0 SErr 0x80000 action
0x2 frozen
[30540.003259] ata1: (irq_stat 0x01100010, PHY RDY changed)
[30540.548784] ata1: waiting for device to spin up (8 secs)
[30548.721383] ata1: soft resetting port
[30548.822362] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[30548.825201] ata1.00: configured for UDMA/100
[30548.825248] ata1: EH complete
[repeats]...

While at the same time, my testing still proceeded without problem.
Are these genuine errors or false alarms?

Do you happen to be using sata_sil on ATI controller? If so, those chipsets don't support hotplug && please use -rc4. If you're using something else, please report what chipset you're using.
