(38262 это аптайм на момент трогания клавиатуры и отвисания)

Спустя неделю после этого события я делал apt-get upgrade в т.ч. ядро (минорное обновление 5.10.113-1, 5.10.136-1) и nvidia (390.144-1, 390.151-1~deb11u1) и ребутнулся. Всё шло хорошо, но, попытавшись спустя несколько часов что-то сделать, обнаружил неработающую клаву и мышь (usb). Заработали после перетыкания их в другие порты (были сзади в углу, вставил спереди). Лог:

Видно как сначала отключились оба устройства, ещё спустя час опять проблема с tsc, но на этот раз без бектрейсов. Обычные порты куда обычно воткнута клава и мышь заработали только после ребута (обычный ребут).

Вчера опять повторилось то же самое

Опять tsc и опять usb. Ребутаться не стал, те два порта сзади так до сих пор не работают и ещё один задний не работают, работают два спереди и три других сзади (хотя питание есть и на неработающих):

Попробую запуститься со старым ядром попозже но вдруг можно что-то сейчас выяснить.

GA-MA785GT-UD3H/GA-MA785GT-UD3H, BIOS F1 07/03/2009

Блин, ну как вот так то?

https://www.gigabyte.ru/products/page/mb/ga-ma785gt-ud3h_10#support-dl

Не хватает энтропии для старта, насколько я помню/понял. Добавь clocksource=jiffies к параметрам ядра, помогает для старого железа.

Биос надо обновлять. Всегда. Лучше выждать месяц-полтора для усушки-утруски (бывало, что фирмвари отзывали после релиза)

Неделю назад запустился со старым ядром, tsc почти сразу сделало то же самое, а вот usb долго работало, уже думал что это всё-таки в новом ядре баг. Но нет, через неделю опять

[621579.970058] ohci-pci 0000:00:12.1: frame counter not updating; disabled
[621579.970073] ohci-pci 0000:00:12.1: HC died; cleaning up
[621579.970216] usb 4-2: USB disconnect, device number 2
[621580.107073] usb 4-3: USB disconnect, device number 4

Нашёл такое https://bugs.launchpad.net/ubuntu/ source/linux/ bug/1634737

Там пишут что это баг в ядре начиная с 4.8, но у меня давно более новое ядро, а началось только сейчас. Там пишут про какой-то периодически запускаемый watchdog, который выключает usb если запускается слишком рано, видимо оно не проявлялось пока таймер работал на tsc, а теперь после бага с tsc начало проявляться.

Хотя, 7 сентября usb слетело до tsc. Но всё-таки мне кажется что причина в таймере так или иначе, он и нарушает работы watchdog-а, и приводит к тому что tsc начинает считаться нерабочим.

Ну и заодно нашёлся способ починить usb без ребута.

rmmod ohci_pci

осознал что теперь отключились все usb порты, а не только сдохшие (а xhci портов нету), сходил за PS/2 клавой

modprobe ohci_pci

Всё заработало.
