Subject: XHCI: sleep inside atomic
Date: Sat, 23 Oct 2010 10:17:14 +0200 [thread overview]
Message-ID: <4CC29A0A.7070405@gmail.com> (raw)
Hi,
Stanse found that commit
USB: xHCI: PCI power management implementation
added xhci_setup_msix->kmalloc(GFP_KERNEL) and request_irq inside
xhci->lock spinlock. As these functions may sleep, this is deadlockable.
Could you fix that?
thanks,
