After a few days of further testing the problem appears again, only not when tryig to connect, but seemingly randomly.
here's my dmesg output. The crash seemingly happens at 'Disabling IRQ #16': [ 801.506696] Call Trace: [ 801.506712] [<c1518c98>] ? printk+0x2d/0x2f [ 801.506725] [<c10aab99>] __report_bad_irq+0x29/0xd0 [ 801.506733] [<c10aaf64>] note_interrupt+0x104/0x150 [ 801.506743] [<c10a948e>] handle_irq_event_percpu+0x9e/0x200 [ 801.506753] [<c1026018>] ? default_spin_lock_flags+0x8/0x10 [ 801.506762] [<c152c6fd>] ? _raw_spin_lock_irqsave+0x2d/0x40 [ 801.506770] [<c1026018>] ? default_spin_lock_flags+0x8/0x10 [ 801.506780] [<c101d43d>] ? __io_apic_modify_irq+0x7d/0x90 [ 801.506788] [<c10a962b>] handle_irq_event+0x3b/0x60 [ 801.506796] [<c10ab6a0>] ? unmask_irq+0x30/0x30 [ 801.506803] [<c10ab6ee>] handle_fasteoi_irq+0x4e/0xc0 [ 801.506808] <IRQ> [<c1533c32>] ? do_IRQ+0x42/0xc0 [ 801.506822] [<c104cf22>] ? sys_gettimeofday+0x32/0x70 [ 801.506830] [<c1533b70>] ? common_interrupt+0x30/0x38 [ 801.506839] [<c1520000>] ? reserve_backup_gdb.isra.11+0x26d/0x2c0 [ 801.506844] handlers: [ 801.506885] [<f835d130>] i915_driver_irq_handler [ 801.506891] Disabling IRQ #16 [ 803.004080] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... render ring idle [waiting on 55440, at 55441], missed IRQ?
