Hello, On a Seagate 1.8T internal drive (with GPT partitioning), and under NetBSD 5.1.2 amd64, on heavy i/o the disk freezes and the system goes unresponsive, obviously stucked waiting for the disk.
There are: ahcisata0: BSY never cleared, TD 0x80 messages too. (Furthermore, there are, when trying to get smart informations via atactl(8): wd1: dos partition I/O error is this the partitioning? A dedicated "hidden" partition precisely for SMART logs?) The disk may be the problem (I mean, it could be a hardware problem with the disk, even if SMART reports everything as reliable, with a high number of read error rate that seems to be "normal" for Seagate drives according to what is found on the Web...). There is kern/47097. What is the status of this? TIA -- Thierry Laronde <tlaronde +AT+ polynum +dot+ com> http://www.kergis.com/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
