[issue676] SB600 HDA audio (Realtek ALC883) glitch - IRQ sharing?
Joe "Floid" Kanowitz <email@example.com> added the comment:
No USB keyboard for me, though if there's any reason to get masochistic I have a
PS/2 to USB adapter in a KVM.
Tried usb01.patch , unfortunately problems remain.
I had the following on uhub0 for the first boot attempt:
ugen0: CPS UPS AE485, rev 1.10/0.01, addr 2
ums0: Microsoft Microsoft 3-Button Mouse with IntelliEye(TM), rev 1.10/3.00,
addr 3, iclass 3/1
I should've taken better notes -- the kernel either enumerated usb0 or uhub0
before locking up quietly, the block cursor on a new line and the keyboard
For the second boot, I unplugged both devices and things went smoothly until the
EHCI driver loaded, with a page fault after enumerating its uhub5: 10 ports with
10 removable, self powered.
More debugging-by-photograph, this time with meat-based OCR:
Fatal trap 12: page fault while in kernel mode
mp_lock = 00000000; cpuid = 0; lapic.id = 00000000
fault virtual address = 0x58
fault code = supervisor read, page not present
instruction pointer = 0x8:0xC048A873
stack pointer = 0x10:0xDA3D3D58
frame pointer = 0x10:0xDA3D3D64
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = Idle
current thread = pri 44 (CRIT)
Stopped at usb_discover+0x70: movl 0x58(%eax),%edx
usb_discover(c3d0a610,1f4,0,0,c062d600) at usb_discover+0x70
usb_event_thread(c3d0a610,0,0,0,0) at usb_event_thread+0x48
kthread_exit() at kthread_exit
Of course, I forgot to disable ehci in loader.conf and see if the sound bug
improved before reporting all this.
Unrelated to *this* bug, some miscellaneous information for the search engines
to pick up:
- Modular X.org ("1.2.0") doesn't like me, as evidenced by the server dying on
signal 11 and/or demonstrating a problem with WaitForSomething() essentially
identical to the one Jeremy C. Reed reported a year ago:
Since the new ati driver, and pretty much every 6.n.n version, doesn't seem to
have improved at autoconfiguration of DVI monitors (or, 9 times out of 10, at
working at all), and the most interesting information I could find had me
sending a note to AMD's Investor Relations that fglrx doesn't cover everyone.
- Every component of Gnome 2.18.1 from pkgsrc-current builds (hooray!) except
for gnome-user-doc. The problem with that seems to be a Python type error, I
need to investigate.
- With BUILD_MAKE_FLAGS=-j 6 set, some of the Gnome packages outside gnome-base
do get into races that have gmake stop on a 'write error.' The really lazy way
to approach this was just to restart the bmake every time where it left off.
- The Gnome System Monitor panel applet (2.18.0) shows a constant "IOWait"
utilization taking up 50% of the "Processor" -- it doesn't break it down by CPU.
This even when top shows the system idle with <1% utilization in all categories.
