SVN r296987 -> r297000 breaks Sil 3124 channel attach

[Michael Butler]

Something between SVN r296987 and r297000 causes the following errors in
dmesg .. and the loss of the attached disks:

siisch0: <SIIS channel> at channel 0 on siis0
device attach: siisch0 attach returned 6
siisch1: <SIIS channel> at channel 1 on siis0
device attach: siisch0 attach returned 6
siisch2: <SIIS channel> at channel 2 on siis0
device attach: siisch0 attach returned 6
siisch3: <SIIS channel> at channel 3 on siis0
device attach: siisch0 attach returned 6

I can't see anything but r297000 causing this :-(
