Hi,

Having added as earlier suggested ...
drivers/usb/host/ehci-hcd.c:611
/* complete the unlinking of some qh [4.15.2.3] */
if (status & STS_IAA) {
if (ehci->reclaim) {
COUNT (ehci->stats.reclaim);
ehci->reclaim_ready = 1;
bh = 1;
} else {
printk(KERN_ERR "AUA: ehci reclaim NULL status: %u\n", status);
}
}
I see now in dmesg
AUA: ehci reclaim NULL status 32 or sometimes 33
I use 2.6.22.13-0.3-default on an Acer Laptop. ATI chipset. Anything
else I can provide?
Regards,
Chris
