Dear Maintainer, My computer showed the new crash report - I had walked away for a bit, and came back to the giant QR code. Very neat. Here's the link (It looks like it encodes a full panic log of the crash. Very cool!) https://kernel-team.pages.debian.net/panic_report/#?a=x86_64&v=7.0.4+deb14-amd64&z=640172491719662804506314019006469450323832465570607302389344144999640056858686670326428228224184344707418072696292501203211948781161157140412494996029030111340388808708581880321221457340149140695130397797262758861753733335454755639376309950917659652737870489619061348468011880387648105539850054810481258064347117208473199332321098415998541218242741810746016525551934319670952266094906335275017394039018658014123386054843275256457982628969947714850452462422832155916983274971016049719711882687528948205277493185667536337439723883924628430412654804630433504865114045102560270189463546999438959298518977388496370189373777229991154491808799302270736814520364054635095075952586983336173946412186328626563993554898473168306085089322419223038098635963684060280645852913187048697638027938485200844892286824960699008376750803384184928198347733347277894788224847294335813397515587112461023416991300915218420568008376196621760755423894012382536777022929600756354511774211473812323546473604519993290397856126686390265434687638117830451182679933299411714410738877480159022156606329255653485831181881782815766983120269237924802368518208510036653920931674691847214707705804853560053350249548916799560624910682755933419650311693582874747232199188492182593673736937809760565860894051685275279352004820344497603040059150327080113545834925380053606237251641415595488257432145800650303120912133466010681501661576422334379131550354242669840100259717131898341494043393124023388750812735126971756577802029434674877620025254664577310665127805480957812524528920325595980275903784744900390750600939197610277151909006613552347019937826589222745668344298643960196776748863248706247388028691635817573472517344194652798427680637396061187248580085934824501026080139576670938467143624350261177321005707947286483291586443516755810524775192371172998759250421663937402561638638180015706995495777660027651056582397437014815175326060011224322150590923298802833391842702093257616763957756600882904648781433295555132451453727472592179063349797246504587350968071351609795005474136141051277909938446234207651841222639008492439066161006957218298792966648750254076793912008910357645848431194219876444142811953325020889627526662263412000068617927860859246653700749316260741539694845563519697822309597952194904690436739204001993865926127739096506888486226933599610947109331338310772059057102355540994346900465677237699900788008670843703439726386514265250314346948169339701539310439628445054935685571678766765190629991335706806221530560665168876393067981844592187177410313023207412617842955886531094591362134687385906766085905397558870664072682023156139346905310581926992029342584538373863765419502599233102857309865064677300166975050199661620141767215796472645141642155182918448596319757927082463513065685199139873210627464137400666656568171624369540647899725231157336547768596831335144604894418102247603484686156201713098217258962302970330211998608867669382635338713402900334361078501028338680809432866121366465921055742952397550581658301507642150755964423969606462190706890186896118058407766176652868141356713540636010196578588521460198130771264328687224613176745768075522157084286790092529029723954151980036942846385255093142269702224897332139275027684010538373146624499846675192528576903136556934586144811255952700694973732634536646786714536193486732060208230961309564319616161627561708105054067874998969494584958042017392344845359350463970961913954689257989341643318450365684130663394891029600560998564793095019069012776794194196937064632184608514008354266267633160386240328034098655047705023219882341394442625358592955048990480764841446659828610769798214666173334327073851269720314521567348822150209487179207948452813674482272954160280147960915948901767124185943429738533985936941429089254137453057033504421246850189317044969760726405659576924805734900725124371345052461058963982341536802529547351426603060521062923125136909329368986781917604666686129917684022154952711664723486609250657881159224402306035675679381156694635246430025672875808075623048944377907805841176463761084012314102791204146494013169274126156870959645343364285264182347420002329068708349112599752105221888485382815425983422331143986343094957651377342170081200924592776063778943152403219662267466198612441790214322295200772196859163281932407685055505322455974281403517175191194965511686126993812229843899297986331397927316189322607644911312298806145746213253527073344346064761652098087518369646577865992086261229612878605652332023144797949548014073204827565201530444039034844858757339120178643121428516820685233142582775174151680676933491282408557252618253271697074263683117092101425238961954810375523016712083639223964069861982322221908442994905083274809053888707743347694099054100569092041723623733156542304100615995723985172955705062768661488958368608453600253306962736746481085755614938789381733687458838012295280623761584158183268462444125912069742367685060725557045995531600057128

It looks like there's a hard kernel panic in the AMD driver at the minute. It could be related to my specific hardware - but I've not seen this specific panic before, usually it's just a brief freeze that can be recovered by replugging a monitor, not a full crash. Two of the monitors were showing the QR code - the third was complete garbage, typical "I've dumped a bunch of random memory into the video framebuffer" kinda stuff. Anyway, an interesting experience, and perhaps a useful demonstration of the new QR code stuff. FYI: I'm running the KDE plasma desktop if that's relevant.

Control: tags -1 moreinfo There are two traces in there. The primary one is amdgpu trying to do atomic memory allocations and failing. Those allocations can fail, as they must not block. This was introduced with https://gitlab.freedesktop.org/drm/amd/-/work_items/4470. The second one should be just a warning and shows up because linux tries to safe the log for the primary problem first. You may find files in /sys/fs/pstore, please provide them. Bastian
