following last post and past experience with 11.04 boot I decided to
take another look at various logs because
- on 10/15 (+ or-) successful boots ONE is UNSUCCESSFUL (no mssgs
whatsoever) AFTER prompted and entering the log in info. the info is
accepted the screen turns to pink colour and the pc locks hard at this
screen; there is no hd activity noticed; the pc must be powered down and
up again and a successful boot can be obtained. there are no messages
whatsoever after gdm successful boot.
looking at dmesg I noticed
[ 50.692374] hda-intel: IRQ timing workaround is activated for card
#2. Suggest a bigger bdl_pos_adj.
also pls take a look at
[ 98.059446] xhci_hcd 0000:02:00.0: WARN: Stalled endpoint
and following; quite a few iterations on this loop. basically sdf is an
external hd device connected to an usb3 adapter card id as follows
02:00.0 USB Controller [0c03]: NEC Corporation uPD720200 USB 3.0 Host
Controller [1033:0194] (rev 03) (prog-if 30 [XHCI])
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at fddfe000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
Kernel driver in use: xhci_hcd
Kernel modules: xhci-hcd
dmesg and kern.log attached. the kernel in use is the one with Seth's
patch applied (see above) ; just an opinion - maybe this usb3
controller-hd combo authentication and config is the cause of the odd
unsuccessful boots ?
