"Native Command Queueing enabled\n", perhaps?
I am seeing concatenated messages every now and then, despite using
options PRINTF_BUFR_SIZE=256
in my kernel config. This occurs only with you ahci driver:
ada0 at ahcich0 bus 0 target 0 lun 0ahcich1: ahci_ch_intr ERROR is
40000001 cs 00000040 ss 00000000 rs 00000040 tfd 6451 serr 00000000
or:
ada0: <HITACHI HTS723216L9SA60 FC2ZC50A> ATA/ATAPI-8 SATA 1.xahcich1:
ahci_ch_intr ERROR is 40000001 cs 00000040 ss 00000000 rs 00000040 tfd
6451 serr 00000000
The appended error message occurs on every access to the empty cd0 device:
ahcich1: ahci_ch_intr ERROR is 40000001 cs 00000200 ss 00000000 rs
00000200 tfd 2451 serr 00000000
ahcich1 is the port to which my internal DVD burner (cd0) is attached.
The controller itself:
