From: Su Hui Date: Fri, 25 Jul 2025 06:01:18 +0000 (+0800) Subject: usb: xhci: print xhci->xhc_state when queue_command failed X-Git-Tag: v6.6.103~506 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d32f522c33a0d6e5e9e0096958086d4aed2dd65;p=thirdparty%2Fkernel%2Fstable.git usb: xhci: print xhci->xhc_state when queue_command failed [ Upstream commit 7919407eca2ef562fa6c98c41cfdf6f6cdd69d92 ] When encounters some errors like these: xhci_hcd 0000:4a:00.2: xHCI dying or halted, can't queue_command xhci_hcd 0000:4a:00.2: FIXME: allocate a command ring segment usb usb5-port6: couldn't allocate usb_device It's hard to know whether xhc_state is dying or halted. So it's better to print xhc_state's value which can help locate the resaon of the bug.
