Well, I've been in a config debug mood lately, so I'm going to go after one more issue. Rather, I'm gonna ask for help here, since I can't find the solution online.
This has been happening since I managed to get ehci working without causing the kernel to freak out. I'm running 5.4 RELEASE p1 (upgrading to p4 later on tonight). The problem happens when I plug in either of my USB key devices (one being a PNY USB Disk, the other a little iPod Shuffle). I am using both ehci and ohci drivers, and AFAICT, the problem only happens with USB2.0 devices. The problem shows up in /var/log/messages as follows: Jul 6 19:41:31 keyslapper kernel: umass0: PNY USB DISK 20X, rev 2.00/1.00, addr 2 Jul 6 19:41:32 keyslapper kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Jul 6 19:41:32 keyslapper kernel: da0: < USB DISK 20X PMAP> Removable Direct Access SCSI-0 device Jul 6 19:41:32 keyslapper kernel: da0: 40.000MB/s transfers Jul 6 19:41:32 keyslapper kernel: da0: 962MB (1970176 512 byte sectors: 64H 32S/T 962C) Jul 6 19:41:32 keyslapper kernel: umass0: Phase Error, residue = 0 Jul 6 19:41:32 keyslapper kernel: (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 The last two lines repeat 16 or 17 times. When I try to mount these, I have no problems. No errors, and everything appears to work fine. I can move files, edit directly on the disk, whatever. So, these messages are an indication of something wierd somewhere, I just don't know if it's purely cosmetic, or if there's really something wrong and my resume is going to get eaten one of these days. I've googled for these messages, and found a lot of reports of the same problem (with few variations), but no solutions or suggestions. I tracked this error message to /usr/src/sys/cam/scsi/scsi_da.c, but I'm not sure exactly where this happens in the device initialization yet (just a quick skim through the code and no understanding of the underlying architecture or USB specs yet). Anyone have any idea?
