Hi, this is your Linux kernel regression tracker speaking. Top-posting for once, to make this easy accessible to everyone. Sadly it looks to me like nobody is going to address this (quite old) regression (that afaic only very few people will hit), despite the rough patch to fix it that was already posted and tested in this thread. Well, guess that's how it is sometimes. Marking it as "on back burner" in regzbot to reduce the noise there: #regzbot backburner: Tested patch available, but things nevertheless got stuck Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. #regzbot poke On 20.01.22 13:54, Thorsten Leemhuis wrote: > Hi, this is your Linux kernel regression tracker speaking. > > On 04.12.21 01:40, Leo Li wrote: >>> -----Original Message----- >>> From: Joakim Tjernlund <Joakim.Tjernlund@xxxxxxxxxxxx> >>> Sent: Thursday, December 2, 2021 4:45 PM >>> To: regressions@xxxxxxxxxxxxx; Leo Li <leoyang.li@xxxxxxx>; >>> Eugene_Bordenkircher@xxxxxxxxxx; linux-usb@xxxxxxxxxxxxxxx; linuxppc- >>> dev@xxxxxxxxxxxxxxxx >>> Cc: gregkh@xxxxxxxxxxxxxxxxxxx; balbi@xxxxxxxxxx >>> Subject: Re: bug: usb: gadget: FSL_UDC_CORE Corrupted request list leads to >>> unrecoverable loop. >>> >>> On Thu, 2021-12-02 at 20:35 +0000, Leo Li wrote: >>>> >>>>> -----Original Message----- >>>>> From: Joakim Tjernlund <Joakim.Tjernlund@xxxxxxxxxxxx> >>>>> Sent: Wednesday, December 1, 2021 8:19 AM >>>>> To: regressions@xxxxxxxxxxxxx; Leo Li <leoyang.li@xxxxxxx>; >>>>> Eugene_Bordenkircher@xxxxxxxxxx; linux-usb@xxxxxxxxxxxxxxx; >>>>> linuxppc- dev@xxxxxxxxxxxxxxxx >>>>> Cc: gregkh@xxxxxxxxxxxxxxxxxxx; balbi@xxxxxxxxxx >>>>> Subject: Re: bug: usb: gadget: FSL_UDC_CORE Corrupted request list >>>>> leads to unrecoverable loop. >>>>> >>>>> On Tue, 2021-11-30 at 12:56 +0100, Joakim Tjernlund wrote: >>>>>> On Mon, 2021-11-29 at 23:48 +0000, Eugene Bordenkircher wrote: >>>>>>> Agreed, >>>>>>> >>>>>>> We are happy pick up the torch on this, but I'd like to try and >>>>>>> hear from >>>>> Joakim first before we do.
