Hi, have you any feedback about your PMP cards? Now I must send out the patch to support the JMP393 PMP card. Maybe I will simply to delay the enough time for PMP SCR as the below: set_current_state(TASK_INTERRUPTIBLE); schedule_timeout(msecs_to_jiffies(50)); /* sleep 50 msecond */ err_mask = sata_pmp_read(link, reg, r_val); > -----Original Message----- > From: Mark Lord [mailto:kernel@xxxxxxxxxxxx] > Sent: Wednesday, November 16, 2011 10:20 PM > To: Huang Changming-R66093 > Cc: Tejun Heo; linux-ide@xxxxxxxxxxxxxxx > Subject: Re: [PATCH] libata-pmp: add schedule timeout to support some PMP > cards > > On 11-11-16 04:00 AM, Huang Changming-R66093 wrote: > >> -----Original Message----- > >> From: Mark Lord [mailto:kernel@xxxxxxxxxxxx] > .. > >>> What's the patch that I need to test ? > >> > >> Found it, tried it, still have a Linux doorstop. > >> Works fine under that other O/S though. > >> > > That’s a bad news.
