-97 is the release kernel, -111 is the current update kernel. And it has
those raid1 issues fixed already, at least the ones that are known. The

Thanks. Good to know that. -111 is currently available to customers? We
may recommend that our customers use that, rather than patching -97
ourselves.
Yes it is, it's generally available through the online updates.
FWIW, I tried the -111 kernel and got a crash with my failing drive. The messages out of the kernel were:
raid1: Disk failure on sdb1, disabling device.
raid1: sdb1: rescheduling sector 176
raid1: sda1: redirecting sector 176 to another mirror
raid1: sdb1: rescheduling sector 184
