Hi, I have a Via-based cardbus combo card that provides two USB 2.0 ports and firewire. It seems to work great, but removal of the card generates the following in 6.2 RELEASE, 6.2 STABLE and 6.3-PRERELEASE: uhub1: detached (null): port 1 reset failed Fatal trap 12: page fault while in kernel mode fault virtual address = 0x44 fault code = supervisor write, page not present instruction pointer = 0x20:0xc07573c0 stack pointer = 0x28:0xd44a7bbc frane pointer = 0x28:0xd44a7bf0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interuppt enabled, resume, IOPL = 0 current process = 35 (usb1) trap number = 12 panic: page fault Uptime: 1m30s Cannot dump. No dump device defined. Is this already known, or is it of interest? Should I file a PR for it (or provide the insert messages)? I saw something that looked similar in an old PR, but that seemed to indicate that USB removal would be fixed in 6.... Regards, Andy
