I have been installing FreeBSD 6.2 on IBM XSeries servers some of which
I need to run external USB drives.
While backing up to a USB hard drive at random times the computer locks
up or reboots with some, but not all of the systems.
The XP3100's work fine and dmesg shows a ntel 82801GB/R ICH7 USB
The XP3400 shows a GENERIC usb 2.0 chipset and a scan of the PCI bus
shows a slightly differant motherboard chipset (I cant remember what it
I set up my Dell server at home with 2 differant USB/PCI cards each with
a differant chipset and got the same type of errors.
The errors on the screen which dont make it to the log are;
sleeping thread (tid 100015, pid 19) owns a non-sleepable-lock
panic: sleeping thread
panic: Trying sleep, but thread marked as sleeping prohimited
[thread pid 13 tid 100002]
stoped at kbd-enter + ox32: leave db7
backup to a usb drive, the problem will occur anywhere from 5 minutes to 5 hours.
