Hi, this is your Linux kernel regression tracker. I noticed a regression report in bugzilla.kernel.org that afaics nobody acted upon since it was reported about a week ago, that's why I decided to forward it to the lists and all people that seemed to be relevant. To quote from https://bugzilla.kernel.org/show_bug.cgi?id=215907 : > Running Manjaro on a Gigabyte B660M DS3H DDR4 with custom 5.17 kernel. Confirmed on other distributions and kernels back to 5.12; issue is not present on most recent 5.11 kernel. dmesg traceback points to i2c DesignWare driver, specifically drivers/i2c/busses/i2c-designware-master.c:369. It seems the msgs struct passed in to i2c_dw_xfer_msg is null. > > Similar issue seems to be reported here: https://lore.kernel.org/lkml/YY5BRrE8bLyvd3PB@xxxxxxxxxxxxxxxxxx/t/ > > lspci output: https://pastebin.com/MwFM2VBJ > dmesg from crashed kernel: https://pastebin.com/t6GsHjkq > kernel config: https://pastebin.com/awrSve5u Could somebody take a look into this? Or was this discussed somewhere else already? Or even fixed? Anyway, to get this tracked: #regzbot introduced: v5.11..v5.12 #regzbot from: Samuel Clark <slc2015@xxxxxxxxx> #regzbot title: i2c: designware: Null pointer exception on resume from S3 #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215907 Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. -- Additional information about regzbot: If you want to know more about regzbot, check out its web-interface, the getting start guide, and the references documentation: https://linux-regtracking.leemhuis.info/regzbot/ https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md The last two documents will explain how you can interact with regzbot yourself if your want to. Hint for reporters: when reporting a regression it's in your interest to CC the regression list and tell regzbot about the issue, as that ensures the regression makes it onto the radar of the Linux kernel's regression tracker -- that's in your interest, as it ensures your report won't fall through the cracks unnoticed. Hint for developers: you normally don't need to care about regzbot once it's involved. Fix the issue as you normally would, just remember to include 'Link:' tag in the patch descriptions pointing to all reports about the issue. This has been expected from developers even before regzbot showed up for reasons explained in 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'.
