Hi,
A switch driver is causing soft lockup on Montavista Linux Kernel 2.6.10
system.
While browsing through the code of the driver. I came across a snippet
where after disabling the interrupts
a call is made to interruptible_sleep_on_timeout().
The code snippet is like
cli();
init_waitqueue_head(&queue);
interruptible_sleep_on_timeout(&queue, USEC_TO_JIFFIES(usec));
thread_check_signals();
sti();
I need to know the side effect of this sort of code, can it be responsible
for the softlockup of the system ? Its a PowerPC based system.
Regards,
Devendra
