Hi Lonnie,
Thanks a lot for your help on the UHCI suspend/resume
support J
I found another problem in QEMU USB support L
I have 5 different types of USB disks at hand. Two of them
can be used properly in Linux and Windows XP guest OS. But other three are not.
After issue “usb_add” to enable those three USB disks in guest domain, the
guest domain becomes extremely slow. It is the same in Linux and Windows
XP guest domain. I checked the log file “/var/log/messages” in Linux guest
domain, and found that it caused the following kernel bug:
Mar 26 04:40:15 linux-FC5 kernel: BUG: soft lockup detected on
CPU#0!
The detailed logs when adding the three USB disks is attached
at the end of this email.
It will be great help if you can give me some instructions
on this issue.
Have anyone else also met this problem?
Thanks
Xiaoyang
