Date: Sat, 24 May 2014 23:40:07 -0400 (EDT) From: David Miller <davem@...emloft.net> To: prashant@...adcom.com Cc: netdev@...r.kernel.org, mchan@...adcom.com Subject: Re: [PATCH net-next] tg3: Override clock, link aware and link idle mode during NVRAM dump From: Prashant Sreedharan <prashant@...adcom.com> Date: Sat, 24 May 2014 01:32:09 -0700 > When cable is not present the clock speed of some of the devices is > reduced based upon power saving mode setting in NVRAM. Due to this > NVRAM reads take long time to complete as a result CPU soft lockup > message is seen. Fix is to override clock, disable link aware and link > idle modes before NVRAM reads and restore them back after the reads > are complete. During this period also check if the thread needs to be > rescheduled and if there are any signals to handle. > > Also decrease the NVRAM command execution timeout value to 1ms. > > Signed-off-by: Prashant Sreedharan <prashant@...adcom.com> > Signed-off-by: Michael Chan <mchan@...adcom.com> Applied to net-next, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
