Hi, when I enable the log option on the / partition using FFSv2 in fstab, I get the following kernel message repeatedly: `wd0: wd_flushcache: status=0x10a8` On my Eee PC 701, this issue seems to be related to the built-in SSD. Does anyone have any suggestions for fixing it?

@"Leufroy"#p19243 Can you show the output of: ```text atactl wd0 identify ```

Leufroy Can you compile a kernel with this patch? (it's for 11.99.3, but should be easy to apply to 10.x):

rvp I applied the patch, rebuilt the NetBSD 10.1 kernel, and installed it on my Eee PC 701. The repeated wd_flushcache errors are now gone. Thank you very much.
