[Kernel-packages] [Bug 1741409] Re: stress smoke test hang with dev test on AWS Xenial kernel
Right now I do not think there is much choice to fix this (other than not touch /dev/hpet on AWS). The linux kernel deliberately wants to set a level triggered interrupt. The xen hypervisor has no support for that (there might be some addition done but certainly not in any released version of Xen). And as "error handling" forcefully crashes the domain. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-aws in Ubuntu. https://bugs.launchpad.net/bugs/1741409 Title: stress smoke test hang with dev test on AWS Xenial kernel Status in linux-aws package in Ubuntu: In Progress Bug description: The test will hang on dev STARTING, and get killed by the timeout setting.

[Kernel-packages] [Bug 1741409] Re: stress smoke test hang with dev test on AWS Xenial kernel
I was booting the same Xenial based HVM guest on the same host (but this time running Bionic / Xen 4.9). This combination does not crash the domain when opening HPET. Though the check and code that would do it is still there. I also found a bug report against xenserver which I believe is based on the same Xen version as we have in Xenial (4.6.5): https://bugs.xenserver.org/browse/XSO-809?focusedCommentId=16484=com.atlassian.jira.plugin.system.issuetabpanels %3Acomment-tabpanel This and the code say that the crash is done because HPET is set to use an unsupported interrupt method (edge/level). Since the Linux guest is the same in both cases, and also the test + crash code, either the hypervisor or maybe the seabios seem to use a different default. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-aws in Ubuntu. https://bugs.launchpad.net/bugs/1741409 Title: stress smoke test hang with dev test on AWS Xenial kernel Status in linux-aws package in Ubuntu: In Progress Bug description: The test will hang on dev STARTING, and get killed by the timeout setting.

[Kernel-packages] [Bug 1741409] Re: stress smoke test hang with dev test on AWS Xenial kernel
I can reproduce this with 4.16-rc2, I've debugged this down to:
drivers/char/hpet.c, hpet_timer_set_irq():
if (irq < HPET_MAX_IRQ) {
spin_lock_irq(_lock);
v = readl(>hpet_config);
v |= irq << Tn_INT_ROUTE_CNF_SHIFT;
writel(v, >hpet_config);
.. the writel to hpet_config causes the reboot.
How to reproduce this issue:
git clone git://kernel.ubuntu.com/cking/stress-ng
cd stress-ng
git revert 0124b250ec205ea3cd6d9d68fb96c03ac294d12f
make
sudo ./stress-ng --dev 1
.. wait a while and it will eventually get around to the /dev/hpet and
opening this causes the hang.
The minimal reproducer is:
#include
#include
#include
#include
#include
int main(void)
{
int fd;
fd = open("/dev/hpet", O_RDONLY | O_NONBLOCK);
if (fd > 0)
close(fd);
exit(0);
}
run this as root and it will cause the reboot.
