Subject: Wait_on_irq
Date: Thu, 27 Aug 1998 10:01:52 +0000 [thread overview]
Message-ID: <marc-linux-ultrasparc-90424190309537@msgid-missing> (raw)
SMP 2.1.99 kernel, ultrap. 1.0.9 2x66MHz ROSS modules SS10
After some concurrent disk-activity I get messages like:
Wait_on_irq CPU#1 stuck at f0117cb8 waiting for f002f95c (local=0, global=1)
Wait_on_irq CPU#1 stuck at f0117cb8 waiting for f002f95c (local=0, global=1)
Wait_on_irq CPU#1 stuck at f0117cb8 waiting for f002f95c (local=0, global=1)
(powercycle is the only way out)
Observing System map at those regions reveal:
f0117b68 T esp_queue
f01183ac T esp_command
f002f934 t timer_bh
f002fdd4 T do_timer
Some kernel locks not properly handeled?
If there's some other kernel I should try, please give me a pointer!
Well perhaps I should wait for the newest ones to work properly on sun4m-SMP
