Ticket # 15731: bmcsensors panics with Dell Poweredge 1750

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Another update fort his issue [kernel panic triggered by bmcsensors}:

The source of the problem are the non-atomic kernel mallocs for device
registration called from an interrupt context - this doesn't seem to be
supported and as observed can crash the kernel.

A possible solution  is to create a kernel thread on initialisation,
leave that thread hanging round while the device scan runs, and finaly
signal the init thread when device scan is complete to finish
initialisation be registing the sensors found during scan.

A patch implementing such a scheme was created by Yvon JEGOU, I'll post
it here again.

Thanks, Martin
