My arm box doesn't succeed to use my esata port multiplier (addonics
sil3726 based). It was working well with 2.6.34.1 and 2.6.34.4 but not
with both 2.6.35.2 and 2.6.35.3. I haven't test other kernels.
The kernels are from http://sheeva.with-linux.com/sheeva/ with for
example the following config
http://sheeva.with-linux.com/sheeva/2.6.35.3/sheeva-2.6.35.3.config
The symptoms are in the console a loop on the esata links. Here is the
start of it:
ata2: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xe frozen
ata2: edma_err_cause=00000010 pp_flags=00000000, dev connect
ata2: SError: { PHYRdyChg DevExch }
ata2: hard resetting link
ata2: SATA link up 3.0 Gbps (SStatus 123 SControl F300)
ata2.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports, feat 0x1/0x9
Can you post or link to the entire dmesg?
Notably, we need to see the probe messages to determine what SATA chip
you are using... From the edma_err_cause config I'd guess sata_mv, but
more info would be useful.
