There are no drives on the SATA interfaces, but there were at one point and I don't remember if it stalled or not. However I do remember them being very slow if I read them both in parallel (16 MB/sec each according to dd and systat) but very fast if I read only one (60 MB/sec) despite the system load being very low. In 5.1 I could only get 16 MB/sec even if I only read from a single drive. I can probably get my hands on more drives if this needs to be reproduced.
Hmm, those hangs are just time spent waiting for drives (that in this case are not there, but it can be difficult to tell).
I know that transferrates are OK on Promise controllers, fx I can dd >50Mb/s off both my Seagates at the same time. However testing on the VIA SATA controller is limmited so far (as I dont have any here in the lab), but I havn't seen any such problems with it.
